Defects engineering of layered double hydroxide-based electrocatalyst for water splitting

Defects engineering of layered double hydroxide-based electrocatalyst for water splitting

(Press-News.org)

In the context of the gradual depletion of fossil fuels and the energy crisis, hydrogen energy has attracted widespread attention due to its ultra-high energy density and eco-friendly properties. However, most of the hydrogen production still relies on fossil fuels, with less than 1 million tonnes produced as low-emission hydrogen in 2021, which means it has limited benefits in mitigating the energy crisis and environmental degradation. Alternatively, hydrogen production via water electrolysis has the advantages of non-polluting products, sustainable regeneration, and abundant reactant storage, making it an attractive option for further development.

Since driving the water electrolysis requires overcoming a significant overpotential, it is essential to use efficient catalysts that can reduce the overpotential. Layered double hydroxide (LDH)-based materials are considered as promising electrocatalysts for water splitting due to the advantages of unique layered structure, flexible tunability, high specific surface area and distinct electron distribution.

However, the low conductivity and limited active sites hinder the industrial applications of LDH-based electrocatalysts. On the other hand, defect engineering is an effective strategy to tune the local surface microstructure and electronic structure, which can efficiently address the drawbacks of LDH.

Recently, Prof. Deli Wang’s team from Huazhong University of Science and Technology, China, reported the recent defect fabrication strategies on LDH and systematically discussed how defects affect the electrocatalytic behavior of LDH. To begin with, the fundamental mechanism of water electrolysis and the challenges faced by LDH as an electrocatalyst for water electrolysis are presented. And then, the superiority of defect engineering for improving the electrocatalytic performance of LDH is presented and a series of defect fabrication strategies on LDH are summarized and discussed in detail. Subsequently, the relationship among catalytic activity, stability, morphology, structure, composition and defect types are emphatically analyzed and discussed. Finally, the challenges and prospects of applying defect engineering on LDH are discussed. The review was published in Chinese Journal of Catalysis (https://doi.org/10.1016/S1872-2067(23)64557-7).

Walking, reminiscing benefit brain health in older Black adults

2024-02-29
An innovative Oregon Health & Science University research program that enlists older Black adults to walk through and reminisce about historically Black neighborhoods in Portland — which now look very different after rapid change through gentrification — may help improve cognitive function, a new study finds. The OHSU project has gained wide interest since its 2016 launch, with similar versions beginning to take root in Seattle and Oakland, California.   Now, newly published research suggests it may improve brain health in a population that’s disproportionately affected by Alzheimer’s disease. The study, published online ...

Uncovering the connections between autism, sensory hypersensitivity

2024-02-29
Supported by a $2 million R01 grant from the National Institutes of Health, the Auerbach Lab at the Beckman Institute for Advanced Science and Technology will examine how different genes associated with autism spectrum disorders may similarly impact our brain’s neurons, resulting in heightened sensitivity to sounds. Autism spectrum disorders are genetically complex, and hundreds of genes are implicated in their development. As a result, some may conclude that autism is a collection of disconnected disorders with comparable symptoms. However, much like how roads converge as they approach a destination, at some level of brain function ...

Researchers decipher mysterious growth habit of weeping peach trees

2024-02-29
A basic premise of how plants grow is that shoots grow up and roots grow down. A new study, published in Plant Physiology, a leading international society journal published by the American Society of Plant Biologists, reveals the answer to a fascinating question: why do weeping tree varieties defy this natural growth pattern? Researchers identified a protein called WEEP that is missing from the Weeping Peach Tree. Their results show how a DNA deletion in just one gene completely changes the localization of the hormone auxin, which ...

The study, led by University of Oxford researchers, has been published today in The Lancet Public Health (video summary available in the notes section).. Lead author Dr Benjamin Goodair, postdoctoral researcher at the Department of Social Policy and Intervention at the University of Oxford, said: ‘This review challenges the justifications for healthcare privatisation and concludes that the scientific support for healthcare privatisation ...

Consistent evidence links ultra-processed food to over 30 damaging health outcomes

2024-02-29
Consistent evidence shows that higher exposure to ultra-processed foods is associated with an increased risk of 32 damaging health outcomes including cancer, major heart and lung conditions, mental health disorders, and early death. The findings, published by The BMJ today, show that diets high in ultra-processed food may be harmful to many body systems and underscore the need for urgent measures that target and aim to reduce dietary exposure to these products and better understand the mechanisms linking ...

Significant proportion of cancer drugs lack proof of added benefit

2024-02-29
Many cancer drugs approved by the European Medicines Agency (EMA) between 1995 and 2020 lack proof of added benefit, particularly those approved through expedited (“fast track”) pathways, finds a study published by The BMJ today. And despite pharmaceutical industry claims that high drug prices are needed to offset research and development (R&D) costs, the results show that more than half of these drugs, including those with minimal or no added benefit, recover R&D expenses within three years. As such, the researchers call for better alignment between regulatory and reimbursement processes, particularly for drugs approved through expedited pathways, to promote development ...
