Amorphous MoOX-Stabilized single platinum atoms with ultrahigh mass activity for acidic hydrogen evolution

Semimetal 1H‐SnS2 Enables High‐Efficiency Electroreduction of CO2 to CO

“…The electrochemical active surface area (ECSA) of the two samples was also evaluated by measuring electrochemical double‐layer capacitance ( C dl ; Figure S27, Supporting Information). [ 53 ] As shown in Figure 3d, the C dl value of 1H‐SnS 2 (58.9 mF cm −2 ) was higher than that of 1T‐SnS 2 (56.2 mF cm −2 ), also further indicating the improved electrochemically active sites of 1H‐SnS 2 . The j CO was further normalized by ECSA in Figure S28 (Supporting Information), 1H‐SnS 2 also affords a greater j CO value than that of 1H‐SnS 2 in a wide potential range from −0.6 to −1.0 V.…”

Rh2S3/N‐Doped Carbon Hybrids as pH‐Universal Bifunctional Electrocatalysts for Energy‐Saving Hydrogen Evolution

“…[30,[32][33][34][35][36] The electrochemical performance of the samples for HER was conducted via a standard three-electrode system with N 2 -saturated alkaline (1.0 m KOH), neutral (1.0 m PBS), and acidic (0.5 m H 2 SO 4 ) electrolytes, and 0.1 m hydrazine was added into these three electrolytes to test the catalytic activity for HzOR. [2,5,8,37] The ohmic drop (i.e., iR drop) correction was performed in all tests except the stability tests. [2,8,38] All presented potentials corresponded to the reversible hydrogen electrode (RHE).…”

Two‐Phase Colloidal Synthesis of Amorphous Iron‐Doped Manganese Phosphate Hollow Nanospheres for Efficient Water Oxidation

“…[ 23,24 ] Compared with crystalline materials, amorphous phase with long‐range disorder structure has the large amount of coordination‐unsaturated sites and sufficient defects, which can provide abundant catalytic active sites for highly efficient water oxidation. [ 25–27 ] For instance, Yu’s group demonstrated that amorphous NiFeMo oxides catalyst experiences a rapider surface self‐reconstruction in the OER process due to the flexible amorphous structure. [ 23 ] Hence, it is anticipated that the exceptional catalytic performance can be realized by combining the individual advantages of hollow nanostructures and amorphous structure.…”
