For NiO materials, there is rarely concern about tuning their d-band states to tailor the OER behaviors. Herein, NiO nanocrystals with doping small amount of La3+ were used to regulate d-band states for promoting OER activity. Density of states calculations based on density functional theory revealed that La3+ doping produced upper shift of d-band center, which would induce stronger electronic interaction between surface Ni atoms and species of oxygen evolution reaction intermediates. Further density functional theory calculation illustrated that La3+ doped NiO possessed reduced Gibbs free energy in adsorbing species of OER intermediate. Predicted by theoretical calculations, trace La3+ was introduced into crystal lattice of NiO nanoparticles. The La3+ doped NiO nanocrystal showed much promoted OER activity than corresponding pristine NiO product. Further electrochemical analysis revealed that La3+ doping into NiO increased the intrinsic activity such as improved active sites and reduced charge transfer resistance. The in-situ Raman spectra suggested that NiO phase in La3+ doped NiO could be better maintained than pristine NiO during the OER.

However, g-C3N4's photocatalytic hydrogen evolution (HER) activity is significantly restricted by the recombination of photocarriers. We find that cobalt sulfide (CoS2) as a cocatalyst can promote g-C3N4 nanosheets (NSs) to realize very efficient photocatalytic H2 generation. The prepared CoS2/g-C3N4 hybrids display highly boosted photocatalytic H2 generation performance and outstanding cycle stability. The optimized 7%-CoS2/g-C3N4 hybrids show a much improved photocatalytic H2 generation rate of 36.2 μmol−1 h−1, which is about 180 times as much as bare g-C3N4 (0.2 μmol−1 h−1). In addition, the apparent quantum efficiency (AQE) of all the samples was computed under light at λ=370 nm, in which the AQE of 7%-CoS2/g-C3N4 hybrids is up to 5.72%. The experimental data and the DFT calculation suggest that the CoS2/g-C3N4 hybrid's excellent HER activity is attributable to the lower overpotential and the smaller Co-H bond activation energy for HER. Accordingly, the CoS2 cocatalyst loading effectively boosts the photocatalytic performance of g-C3N4 for H2 evolution. The project promotes fast development of high-efficiency photocatalysts and low-cost for photocatalytic H2 generation.</div>","PeriodicalId":33573,"journal":{"name":"Nano Materials Science","volume":"5 2","pages":"Pages 202-209"},"PeriodicalIF":9.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44406068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
