Application of a deep eutectic solvent to prepare nanocrystalline Ni and Ni/TiO2 coatings as electrocatalysts for the hydrogen evolution reaction

Effect of TiO2 Concentration on Microstructure and Properties of Composite Cu–Sn–TiO2 Coatings Obtained by Electrodeposition

“…Composite coatings Cu–Sn–SiC [ 28 ], Cu–Sn–graphite–Al 2 O 3 [ 29 ], and Cu–Sn–TiO 2 [ 25 , 30 , 31 ] with improved tribological and physicomechanical properties were obtained electrochemically. Titanium(IV) oxide due to its physical-mechanical and photocatalytic properties, as well as chemical resistance in corrosive media, is widely used as a hardening phase in the deposition of composite coatings [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ]. Galvanic coatings modified with TiO 2 nanoparticles can exhibit photocatalytic properties, which is well demonstrated in the literature [ 33 , 34 , 35 ].…”

Electrocatalytic hydrogen evolution properties of anionic NiS 2 ‐Ni(OH) 2 nanosheets produced on the surface of nickel foam

“…In the electrolysis of water, the cathode and the anode simultaneously produce H 2 and O 2 . These two reactions are the hydrogen evolution reaction (HER) of the cathode and the oxygen evolution reaction (OER) of the anode. Both reactions determine the efficiency of electrolyzing water.…”

Facile Synthesis of Cobalt Oxide as an Efficient Electrocatalyst for Hydrogen Evolution Reaction

“…Because of their Pt-like catalytic behaviors for HER, well electrocatalysts originated from the most abundant elements (Co, Fe, Mo, Ni, Ti, W, and so on) has experienced rapid development over the past decade (Jung et al, 2014;Kuznetsov et al, 2019;Liu et al, 2020). Scientists design and develop various catalysts including transition metal oxides (CoO, Fe 3 O 4 , MoO 2 , TiO 2 , WO 2 ) (Park and Kolpak, 2019;Protsenko et al, 2019;Qian et al, 2019;Li L. et al, 2020;Li S. et al, 2020), metal sulfides (CoS, CuS, FeS 2 , MoS 2 , NiS 2 , V 3 S 4 , WS 2 ) (Li et al, 2018;Shi et al, 2019;Singh et al, 2019;Cao et al, 2020;Hao et al, 2020;Thangasamy et al, 2020), metal carbides (MoC 2 , WC) (Ji et al, 2018;Hussain et al, 2019), metal phosphides (CoP, NiP, FeP, WP, MoP) (Ojha et al, 2017;Zhang C. et al, 2018;Wang P. et al, 2019;Ji et al, 2020;Lin et al, 2020), metal selenides (CoSe 2 , MoSe 2 , NiSe 2 , WSe 2 ) (Wang et al, 2012(Wang et al, , 2020Chen et al, 2020;Nam et al, 2020) and metal boron (Huang et al, 2019;.…”
