An ultrathin 2D NiCo-LDH nanosheet decorated NH2-UiO-66 MOF-nanocomposite with exceptional chemical stability for electrocatalytic water splitting

“…In this regard, the conversion of solar/electric energy into chemical energy via photoelectric/electrically power-driven H 2 O splitting to obtain H 2 fuel is one of the most promising and realistic ways. [1][2][3] To achieve these objectives, there is an urgent requirement for effective electrocatalysts to improve the reaction kinetics since electrocatalytic water splitting is an energyintensive process. 4 As of now, Pt is acknowledged as the best HER electrocatalyst in acidic solutions, whereas noble metalbased materials like Ru, Ir, RuO 2 , and IrO 2 are regarded as the benchmark OER electrocatalysts in alkaline as well as acidic aqueous solutions.…”

“…So far various transition metal-based catalysts have been investigated for this technique. 3,6,7 However, further work is needed to develop and synthesize novel robust and efficient inorganic electrocatalysts with excellent stability. In this context, MOFs, as a class of highly crystalline materials with a dynamic, adjustable porous structure and an abundance of active sites, are currently assumed to be suitable for OER and HER electrocatalytic performance.…”

Exploring efficient hydrogen evolution electrocatalysts of nonmetal atom doped Mo2CO2 MXenes by first-principles screening

“…1,2 Electrocatalytic hydrogen evolution has the potential to become one of the most effective approaches to produce hydrogen in a sustainable manner. 3,4 Yet the Pt-based materials are the most efficient catalysts for the HER. 5,6 Although noble Pt metal catalysts have been relied on for efficient hydrogen production, their large-scale applications have been severely hindered due to their scarcity, high price and weak durability.…”

Fabrication of High Quality Bornite and Chalcopyrite Thin Films by Aerosol-Assisted Chemical Vapor Deposition

“…Metal chalcogenides, including transition metal chalcogenides (TMCs), constitute an important and attractive class of compound semiconductor materials that are promising candidates for photo­(electro)­chemical and photoelectric energy generation devices. − Examples of these materials include CdTe, TaS 2 , CdS, MoS 2 , MoSe 2 , CdSe, ZnSe, Cu 2 MoS 4 , CuInSe 2 (CIS), CdZnTe (CZT), Cd­(In, Ga)­Se 2 (CIGS), Cu 2 FeSnS 4 (CFTS), CuPbSbS 3 , Cu 2 ZnSnS 4 (CZTS), and Cu 2 ZnSnSe 4 (CZTSe). TMC compounds can be categorized with respect to the number of distinct elements they contain; binary (e.g., CuS and FeS 2 ), ternary (Mo,W)­S 2 , Mo­(SSe) 2 , CuFeS 2 , Cu 5 FeS 4 ), and quaternary (e.g., Cu 2 ZnSnS 4 ).…”
