Tissue paper-derived porous carbon encapsulated transition metal nanoparticles as advanced non-precious catalysts: Carbon-shell influence on the electrocatalytic behaviour

A new approach for ultra-high adsorption of cationic methylene blue in a Zr-sulfonic-based metal–organic framework

“…3 Hence, removing organic dyes from wastewaters is extremely necessary before discharging them into the natural environment. There are many approaches to remove these pollutants, such as catalysis, [4][5][6] advanced oxidation processes, 7 occulation, 8 membrane ltration, 9 and electrolysis. 10 Apart from these methods, adsorption has emerged as the most efficient technique to purge hazardous substances from wastewater due to its eetness, low cost, high yield, insignicant dangerous by-products, and simplicity.…”

Pb(Ⅱ) adsorption characteristics of magnetic GO-hydroxyapatite and the contribution of GO to enhance its acid resistance

“…Due to the excellent physicochemical properties, nanomaterials have currently attracted extensive attention in the fields of electrocatalysis (Ahsan et al, 2021), photocatalysis (Xiong et al, 2020), cancer (Sanad et al, 2019) and water treatment (Akın Sahbaz et al, 2018).…”

N-Doped Graphene as an Efficient Metal-Free Electrocatalyst for Indirect Nitrate Reduction Reaction

“…Carbon nanomaterial is widely used as electrocatalysts due to their chemical stability and good conductivity [ 37 , 38 , 39 , 40 , 41 , 42 ]. Graphene, the typical carbon nanomaterial with two-dimensional structure, has been demonstrated to facilitate the electrochemical reduction of nitrate into nitrite [ 43 ], which is regarded as the rate-determining step in the entire process of nitrate reduction [ 44 , 45 , 46 , 47 ].…”

“…By comparison, cheap and earth-abundant metal-free electrocatalysts with high activity and good stability in acidic conditions are highly desired. Carbon nanomaterial is widely used as electrocatalysts due to their chemical stability and good conductivity [37][38][39][40][41][42]. Graphene, the typical carbon nanomaterial with twodimensional structure, has been demonstrated to facilitate the electrochemical reduction of nitrate into nitrite [43], which is regarded as the rate-determining step in the entire process of nitrate reduction [44][45][46][47].…”
