Defect Engineering on Carbon-Based Catalysts for Electrocatalytic CO2 Reduction

“…Overall, the ECR activity of all defect types is better than perfect sp 2 carbon (bulk graphene), with octagonal and pentagonal defects performing best. Kang et al [ 93 ] synthesized a hierarchical porous carbon catalyst rich in intrinsic defects (DHPC) (Fig. 3 h).…”

Electrodeposition of Ni on MWNTs as a promising catalyst for CO2RR

“…Carbon‐based materials have also been explored with promising results 4,12,13 . However, due to the difficulty to create uniform defects and vacancies on the carbon‐based materials, the catalytic performance is not desired for real applications 14‐17 …”

Cu atomic clusters on N-doped porous carbon with tunable oxidation state for the highly-selective electroreduction of CO2

“…Many efficient CO 2 RR electrocatalysts, such as different metals or metal oxides, have been studied. [10][11][12][13][14][15][16][17][18] Among the various types of catalysts, Cu as the most promising candidate can catalyse CO 2 into a wide range of products, including C1 species (CO, CH 4 , HCOOH), C2 species (C 2 H 4 , C 2 H 5 OH), and even C3 species (C 3 H 7 OH). 19,20 However, such products are typically hard to separate, resulting in low selectivity.…”
