High-Density CoSe2 Sites Embedded within 2D Porous N-Doped Carbon for High-Performance Oxygen Reduction Reaction Electrocatalysis

“…16 Although cobalt selenides exhibit excellent theoretical and experimental activities in electrocatalysis, these bare selenides are prone to agglomeration, and their low stability and insufficient conductivity severely limit their large-scale industrial application in oxygen electrocatalysis. 17 Several strategies have been explored to improve the stability and conductivity of catalysts, such as heterojunction design, 18,19 alloy structure construction, 20,21 and carbon coating. 22,23 Among them, encapsulating transition-metal-based compounds in carbon substrates has attracted widespread attention.…”

“…Several strategies have been explored to improve the stability and conductivity of catalysts, such as heterojunction design, , alloy structure construction, , and carbon coating. , Among them, encapsulating transition-metal-based compounds in carbon substrates has attracted widespread attention. The inert carbon layer can effectively protect the stability of the crystal structure and prevent it from being etched by harsh electrolytes.…”

Air-Calcined Fe/Ni-Based Metal–Organic Framework Nanosheets for Oxygen Evolution Reactions

“…Consequently, there is a pressing need to develop environmentally friendly and highly efficient energy storage technologies. 1 Researchers have devoted their efforts to identifying and harnessing materials that can replace traditional energy sources, thus achieving zero environmental pollution while pursuing efficient energy conversion.…”

Efficient electrocatalytic oxygen reduction reaction of thermally optimized carbon black supported zeolitic imidazolate framework nanocrystals under low-temperature

“…Here, the oxygen reduction reaction (ORR) is one of the important half-cell reactions and is considered the performance determining reaction. [1][2][3][4][5][6][7][8][9][10] Platinum metal nanoparticles dispersed on carbon black materials (usually denoted as Pt/C) are typical active electrocatalysts. 1 However, their high cost factor and unsatisfactory catalytic durability hinder the widespread implementation of electrochemical technologies.…”

“…4,5,11,12,22,23 Pre-fabricated conducting carbon supports have been used to support polymer, MOF or ZIF structures and exploited for their electrocatalytic activities under low carbothermal modulation. For example, reduced graphene-oxide (rGO), 4,15,29,31 carbon nanotube (CNT), 9,18,21,27 carbon cloth/paper (CC/CP), carbon nanober (CNF), 2,10,13,19,32,33 small metal-coordinated molecules/polymers or MOFs-derived carbon (MDC) templated and/or ordered mesoporous carbon (OMC) [2][3][4]6,7,9,11,16,22,23,[27][28][29][30][31][32][33][34][35][36] have been used. However, such pre-synthesized carbon supports offer no commercial/scalable benets as they require complex and prolonged chemical modications.…”
