Hierarchical porous carbon materials have been derived through CO2 conversion by using NaBH4 as a reducing agent and CaCO3 as a nano-template. The CaCO3-templated porous carbons (CPCs) feature an interconnected three-dimensional structure with hierarchical pores favorable for electrochemical energy storage. Notably, CPC1_700 prepared with an identical mass of CaCO3 and NaBH4 at 700 °C shows a very...
This study investigated the synthesis of hierarchically porous heteroatom-doped (B and N) carbon materials from CO2 or flue gas by CO2 conversion using NaBH4 as a reducing agent and their applications as supercapacitors. The resultant carbon materials exhibited a high specific capacitance of 210F/g at 1A/g, which is higher than that found in a typical activated carbon. This is because their hierarchical...
