Two decades-long catalytic journey has borne industrial fruit—greener, cleaner, and smarter. Fischer–Tropsch synthesis (FTS) and heterogeneous hydroformylation are two cornerstone processes in modern chemical manufacturing. They convert syngas (a mixture of CO and H₂, typically derived from coal or biomass) into hydrocarbons and oxygenates that underpin fuel, plastics, and pharmaceutical industries. Yet for over a century, challenges in selectivity, catalyst longevity, and process integration have limited their broader industrial deployment—until now.
In a newly published account in Chinese Journal of Catalysis (DOI: 10.1016/S1872-2067(25)64701-2), a team led by Prof. Yunjie Ding and Prof. Li Yan at the Dalian Institute of Chemical Physics (DICP), in collaboration with Dr. Ronghe Lin (Zhejiang Normal University) and Dr. Shenfeng Yuan (Zhejiang University), presents a comprehensive roadmap of scientific breakthroughs that move these legacy reactions into a modern era of green chemistry.
A New Generation of Co–Co₂C Catalysts for FTS. The team developed a series of carbon-supported cobalt–cobalt carbide (Co–Co₂C) catalysts that fundamentally reshape FTS performance. By tuning the interface between metallic cobalt and its carbide phase, they achieved dual-active sites that guide syngas molecules through controlled C–C coupling and CO insertion steps—enabling selective formation of long-chain α-alcohols and olefins. These insights, backed by DFT calculations and operando spectroscopy, translated into real-world application. A 150 kt/a industrial slurry-phase reactor based on the Co–Co₂C system has been in full operation since 2020 in Yulin, China—the first such carbon-supported Co catalyst in global use.
Single-Atom Rh Catalysts Transform Hydroformylation. To overcome the well-known separation and precious metal leaching issues of homogeneous Rh-based hydroformylation, the researchers pioneered a porous organic polymer (POP)-anchored single-atom Rh catalyst: Rh₁/POPs-PPh₃. The catalyst features robust multi-dentate Rh–P bonds, delivering exceptional activity, transient sulfur poisoning and self-recovery, and structural integrity under harsh industrial conditions. In 2020, this innovation was scaled up to the world’s first commercial heterogeneous hydroformylation plant in Zhenhai, China, producing 50 kt/a of n-propanol from ethylene with unprecedented catalyst efficiency and longevity. The losses of Rh and ligand are negligible, and the reactor operates continuously, marking a transformative step in green olefin functionalization.
Extending the Value Chain to High-Value Products. Based on these catalytic platforms, they also developed integrated separation schemes and extraction processes to isolate alcohols and paraffins from complex FTS product mixtures with high purity. They further advanced value-chain by converting the FTS-derived α-alcohols into high-value commodities such as, α-olefins, lubricants, and fatty acids, which are not commonly synthesized from coal.
From bench-scale insights to commercial milestones, this research illustrates how a “mechanism-insight-to-green-manufacture” approach—grounded in catalyst design and process coupling—can unlock new industrial opportunities for syngas utilization, especially in coal-rich economies transitioning toward low-carbon futures.

□ The research team led by Senior Researchers Yoonhee Lee from the Division of Biomedical Technology and Gyogwon Koo from the Division of Intelligent Robot at DGIST (under President Kunwoo Lee) has developed a technology that distinguishes lung cancer gene mutations solely by measuring the “stiffness” of exosomes—tiny particles released from cancer cells in the bloodstream—using atomic force microscopy (AFM). Their study enables rapid and precise analysis of individual exosomes and is expected to advance into a new liquid biopsy-based diagnostic technique for lung cancer.

When Black and Latino youth aspire toward careers in science and technology, their confidence in exploring career possibilities and how they think society views their ethnic-racial group can play a crucial role in whether their dreams take root.
Such is a finding of a study by UC Riverside associate professor of psychology Aerika Brittian Loyd, UCR doctoral candidate Tate LeBlanc, and co-authors published in the Journal for STEM Education Research.
Middle and high school students who voiced higher expectations of success in exploring different career paths — along with perceptions that their racial ...
The presence of humans and human infrastructure in U.S. national parks has lasting effects on the behaviours of the large animals that call them home, according to a new study.
“Wildlife all around the world fear people and avoid areas of high human activity, but it was surprising to see that this holds true even in more remote protected areas,” said Dr. Kaitlyn Gaynor, a zoologist at the University of British Columbia and lead author of the paper published today in the Proceedings of the Royal Society B.
Researchers tracked 229 animals from 10 species across 14 national parks and protected areas using GPS collar data from 2019 to 2020, ...
In a discovery that deepens our understanding of animal social bonds, a study led by University of Oxford researchers in collaboration with the University of Leeds has demonstrated that wild great tits exhibit clear behaviours signalling ‘divorce’ long before the breeding season. The findings, published today (30 July) in Proceedings of the Royal Society B, provide valuable new insights into how animals navigate complex social decisions. provide valuable new insights into how animals navigate complex social decisions.

Osaka, Japan – DNA holds the instructions that make us who we are. If we want to read those instructions, say to understand our predisposition to genetic disorders, we need to carefully ‘unzip’ DNA’s iconic double-helix structure. This is neither easy nor fast, and the process involves intense heating and chemicals that can damage the DNA.
Now, in a new study published in ACS Nano, a research team led by The University of Osaka has developed a novel technology for making the unzipping process much easier. Their invention uses a miniature heater to precisely and gently unzip the DNA double helix.
The device uses a nano-sized platinum coil. As the DNA strand reaches ...
Women politicians in Europe receive uncivil tweets regardless of how known they are – and woman also receive more identity-based attacks than other politicians, revealed a new study in Politics & Gender, published on behalf of the American Political Science Association by Cambridge University Press.
This study used a machine learning approach to analyse over 23 million tweets addressed to politicians in Germany, Spain, the United Kingdom, and the United States, to determine the degree of incivility that female politicians face. Women in politics frequently report serious online harassment, yet the extent of this harassment and how it compares ...

UK teens who currently vape are as likely to take up smoking as their peers in the 1970s, despite a substantial fall in the prevalence of teenage smoking over the past 50 years, suggests a long term intergenerational study published online in the journal Tobacco Control.
The likelihood of starting to smoke among teens who don’t vape was around 1.5%, but 33% among those who do, the findings indicate.
It’s not entirely clear if the rise in popularity of e-cigarettes (vapes) among teens threatens the steady decline in the prevalence of cigarette smoking in this age group, say the researchers, as the ...
A higher intake of ultra processed food (UPF) is linked to an increased risk of lung cancer, suggests research published online in the respiratory journal Thorax.
Further research is warranted in different population groups, but limiting consumption of these foods may help curb the global toll of the disease, say the researchers.
Lung cancer is the most common cancer in the world. And in 2020 alone there were an estimated 2.2 million new cases and 1.8 million deaths from the disease worldwide, they note.
UPF typically undergo multiple processing steps, contain long lists of additives and preservatives, and are ready-to-eat or heat. High consumption has been linked to a heightened risk of ...
