In article number 1904043, Haohong Duan, Yun Kuang, Xiaoming Sun, and co‐workers use ruthenium, a much cheaper noble metal (the price is about 1/3 of Pt metal) with Pt like adsorption energy to H, to synthesize amorphous RuSx nanoparticles with atomically isolated active sites adhered on the surface of sulfur‐doped graphene for hydrogen evolution, affording Pt‐like or even higher activity in the entire...
Electrocatalytic hydrogen evolution reaction (HER) is an efficient way to generate hydrogen fuel for the storage of renewable energy. Currently, the widely used Pt‐based catalysts suffer from high costs and limited electrochemical stability; therefore, developing an efficient alternative catalyst is very urgent. Herein, one pot hydrothermal synthesis is reported of amorphous ruthenium‐sulfide (RuS...
Hydrogen evolution reaction (HER) has prospect to becoming clean and renewable technology for hydrogen production and Ni–Mo alloy is among the best HER catalysts in alkaline electrolytes. Here, an in situ topotactic reduction method to synthesize ultrathin 2D Ni–Mo alloy nanosheets for electrocatalytic hydrogen evolution is reported. Due to its ultrathin structure and tailored composition, the as‐synthesized...
A pine‐shaped Pt nanostructured electrode with under‐water superaerophobicity for ultrahigh and steady hydrogen evolution reaction (HER) performance is successfully fabricated by a facile and easily scalable electrodeposition technique. Due to the lower bubble adhesive force (11.5 ± 1.2 μN), the higher bubble contact angle (161.3° ± 3.4°) in aqueous solution, and the smaller size of bubbles release...
The adhesion of as‐formed gas bubbles on the electrode surface usually impedes mass‐transfer kinetics and subsequently decreases electrolysis efficiency. Here it is demonstrated that nanostructured MoS2 films on conductive substrates show a faster hydrogen evolution reaction (HER), current increase, and a more‐stable working state than their flat counterpart by significantly alleviating the adhesion...
