Ef fective and robust catalyst is the core of water splitting to produce ***, we report an anionic etching method to tailor the sulfur vacancy(VS) of NiS_(2) to further enhance the electrocatalytic performance for hydrogen evolution reaction(hER). With the VS concentration change from 2.4% to 8.5%, the h* adsorption strength on S sites changed and NiS_(2)-VS 5.9% shows the most optimized h* adsorption for hER with an ultralow onset potential(68 m V) and has long-term stability for 100 h in 1 M kOh media. In situ attenuated-total-reflection Fourier transform infrared spectroscopy(ATR-FTIRS) measurements are usually used to monitor the adsorption of intermediates. The S-h* peak of the Ni S_(2)-VS 5.9% appears at a very low voltage, which is favorable for the hER in alkaline media. Density functional theory calculations also demonstrate the Ni S_(2)-VS 5.9% has the optimal |ΔG^(h*)| of 0.17 e V. This work offers a simple and promising pathway to enhance catalytic activity via precise vacancies strategy.

Aqueous-phase reforming(APR)is an attractive process to produce bio-based hydrogen from waste biomass streams,during which the catalyst stability is often challenged due to the harsh reaction *** this work,three Pt-based catalysts supported on C,AlO(Oh),and ZrO_(2)were investigated for the APR of hydroxyacetone solution in afixed bed reactor at 225℃and 35 *** them,the Pt/C catalyst showed the highest turnover frequency for h_(2)production(TOF of 8.9 molh_(2)molPt^(-1)min^(-1))and the longest catalyst *** the AlO(Oh)and ZrO_(2)supported Pt catalysts,the side reactions consuming h_(2),formation of coke,and Pt sintering result in a low h_(2)production and the fast catalyst *** proposed reaction pathways suggest that a promising APR catalyst should reform all oxygenates in the aqueous phase,minimize the hydrogenation of the oxygenates,maximize the WGS reaction,and inhibit the condensation and coking reactions for maximizing the hydrogen yield and a stable catalytic performance.
