Harnessing Wind Energy for Ultraefficient Green Hydrogen Production with Tin Selenide/Tin Telluride Heterostructures

“…The results indicate that all the catalysts display a Type IV isotherm. [ 31 ] Specifically, SnSe/SnTe exhibits a significantly increased surface area (65.6 m 2 g −1 ) compared to SnSe/SnS (45.8 m 2 g −1 ), SnS/SnTe/NF (45.2 m 2 g −1 ), SnSe/NF (36.4 m 2 g −1 ), SnS/NF (22.2 m 2 g −1 ), and SnTe/NF (17.0 m 2 g −1 ). [ 64 ] The results collectively affirm the successful formation of phase‐rich interfaces in these heterostructures, achieved through a straightforward one‐pot hydrothermal technique.…”

“…[ 29 ] Even though the noble Pt‐based catalysts are considered benchmark electrocatalysts for HER and MOR, in the case of HWE, the noble metals lead to the total oxidation of methanol to produce CO 2 , again harming the environment. [ 30,31 ] In light of these challenges, researchers focus on developing cost‐effective non‐noble catalysts for HWEs with highly selective MOR without compromising hydrogen production efficiency. [ 32 ] Recently, a variety of non‐noble metal sulfides, [ 33,34 ] selenides, [ 35 ] nitrides, [ 36,37 ] phosphides, [ 6,38 ] oxides, [ 39 ] borides, [ 40 ] and hydroxides, [ 32,41 ] were reported as electrocatalysts for water electrolyzers.…”

Supporting critical raw material circularity – upcycling graphite from waste LIBs to Zn–air batteries

“…Multi-metal catalyst materials have good ORR/OER bifunctional electrocatalytic activity due to the synergistic effect of the metals, but the concrete effects of multi-metallic catalyst materials are still under debate. 49,50,76 Performance as an air electrode catalyst in zinc-air batteries…”

Composite electrodes with superior catalytic activity in methanol electro-oxidation fabricated using ternary NiO–CuO–ZnO mixed metal oxides

“…The efficient oxidation of methanol in these fuel cells is due to its low molecular complexity. 24 Methanol is a vital fuel due to its high octane number, its heat of vaporization, and fuel conversion efficiency as compared to other fuels, e.g., gasoline. 25 Numerous efforts have been made to develop an electrocatalyst that can boost the efficiency of methanol fuel cells by enhancing methanol oxidation and oxidation-reduction reactions.…”
