Techniques for anionic defect engineering in transition metal oxides and mechanisms of how anion defects affect their oxygen reaction activities.
Abstract Developing low‐cost, high‐performance electro‐catalysts is essential for large‐scale application of electrochemical energy devices. In this article, reported are the findings in understanding and controlling oxygen defects PrBa 0.5 Sr Co 1.5 Fe O 5+ δ (PBSCF) significantly enhancing rate evolution reaction (OER) reported. Utilizing surface‐sensitive characterization techniques first‐principle calculations, it found that excessive vacancies promote OH − affiliation lower theoretical...
Abstract Developing cost effective electrocatalysts with high oxygen evolution reaction (OER) activity is essential for large‐scale application of many electrochemical energy systems. Although the impacts either lattice strain or defects on OER performance oxide catalysts have been extensively investigated, effects both factors are normally treated separately. In this work, coupled and deficiency electrocatalytic La 0.7 Sr 0.3 CoO 3−δ (LSC) thin films grown single crystal substrates (LaAlO3...
Transition metal dichalcogenides (TMDs) have attracted much attention due to their promising optical, electronic, magnetic, and catalytic properties. Engineering the defects in TMDs represents an effective way achieve novel functionalities superior performance of devices. However, it remains a significant challenge create controllable manner or correlate nature with functionalities. In this work, taking single-layer MoS2 as model system, controlled densities are generated by 500 keV Au...
Abstract Developing highly efficient and cost-effective oxygen evolution reaction (OER) electrocatalysts is critical for many energy devices. While regulating the proton-coupled electron transfer (PCET) process via introducing additive into system has been reported effective in promoting OER activity, controlling PCET by tuning intrinsic material properties remains a challenging task. In this work, we take double perovskite oxide PrBa 0.5 Sr Co 1.5 Fe O 5+δ (PBSCF) as model to demonstrate...

Peroxymonosulfate (PMS)-based advanced oxidation process (AOP) has attracted great attention as an effective technique for oxidatively decomposing organic pollutants. The PMS activation mechanisms, nevertheless, are still ambiguous in many cases, and, thus, controlling pathways efficient pollutant removal remains challenging. In this work, taking defective PrBa0.5Sr0.5Co1.5Fe0.5O5+δ (PBSCF) a model system, we demonstrate that oxygen vacancies (Vo••) strongly promote PMS-based AOP, and...
Electrochemical water splitting has attracted great attention as a promising technique for efficiently producing hydrogen with high purity. Developing noble metal-free electrocatalysts good activity the evolution reaction (HER) and oxygen (OER) is critical achieving economical water-splitting devices. In this work, we report facile strategy to construct Ni(OH)2/MoS2 heterostructure via defect-mediated metal ion adsorption. Abundant defects were introduced into MoS2 nanosheets using...
In article number 1901783, Bote Zhao, Yan Chen, Meilin Liu, and co-workers report their finding in understanding controlling oxygen defects PrBa0.5Sr0.5Co1.5Fe0.5O5+δ (PBSCF) for significantly enhancing the evolution reaction activity. Oxygen vacancies are found to promote OH− affiliation lower energy formation of O*. However, also increase band gap O 2p center PBSCF.
