Strain-promoted conductive metal-benzenhexathiolate frameworks for overall water splitting

Theoretical insights into the two-dimensional gallium oxide monolayer for adsorption and gas sensing of C4F7N decomposition products

“…Strain engineering ( ε = ( a ′ − a )/ a ) is able to accurately adjust the electronic properties of the adsorption systems and further regulate the adsorption energy, thus improving the sensitivity of the substrate material to the target gas. 46 a ′ and a represent the lattice constants of the Ga 2 O 3 with and without strain, respectively. Biaxial strain ranging from −6% to 6% is applied to adjust the gas sensing performance of Ga 2 O 3 for C 3 F 6 as described in Fig.…”

Three-Dimensional Heterostructured CoSe2/MoSe2@CC as Trifunctional Electrocatalysts for Energy-Efficient Hydrogen Production

“…However, high temperatures and immoderate carbon dioxide emissions are not conducive to further development in this way . Electrolytic water is an environmentally friendly, cost-effective high-purity hydrogen production strategy, which can convert renewable energy with intermittent (such as solar and wind energy) into hydrogen. , Therefore, electrolysis of water is a good strategy to convert stable and intermittent energy into hydrogen energy that can be stored. − The entire water electrolysis process can intriguingly generate pure hydrogen and oxygen via two slow reduction-oxidation reactions: cathodic HER (2H + (aq) + 2e – → H 2(g) ) and the four-electron slow transfer process for anodized OER (2H 2 O (l) → 4e – + 4H + (aq) + O 2(g) ). − Theoretically, the electrocatalysis of water requires only an electric potential of 1.23 V being the result that the potential corresponds with HER (0 V) and OER (1.23 V), while actual equilibration voltages to overcome high reaction potential energy are higher , due to severely inefficient kinetics of both OER and HER. Therefore, it is key to reduce OER overpotential and thus improve the energy efficiency of hydrogen generation.…”

ZIF-67-derived CuCo2S4@CoS2 as an efficient bifunctional electrocatalyst for overall water splitting

“…4,5 Electrolysis of water involves two halfreactions: hydrogen evolution reaction (HER) at the cathode and oxygen evolution reaction (OER) at the anode, and efficient catalysts are required to reduce the overpotential of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) or to operate under high current conditions. [6][7][8][9][10] Platinum-and ruthenium-based catalysts are the most effective HER and OER catalysts, 11,12 but their limited reserve seriously affects their further applications. 13 Therefore, it is necessary to develop effective non-noble metal catalysts for hydrogen evolution and oxygen evolution reactions.…”
