Biomass-Derived Porous Carbon Materials for Supercapacitor

Abstract: The fast consumption of fossil energy accompanied by the ever-worsening environment urge the development of a clean and novel energy storage system. As one of the most promising candidates, the supercapacitor owns unique advantages, and numerous electrodes materials have been exploited. Hence, biomass-derived porous carbon materials (BDPCs), at low cost, abundant and sustainable, with adjustable dimension, superb electrical conductivity, satisfactory specific surface area (SSA) and superior electrochemical stability have been attracting intense attention and highly trusted to be a capable candidate for supercapacitors. This review will highlight the recent lab-scale methods for preparing BDPCs, and analyze their effects on BDPCs' microstructure, electrical conductivity, chemical composition and electrochemical properties. Future research trends in this field also will be provided.

A Simple Way to Prepare C–N-Codoped TiO2 Photocatalyst with Visible-Light Activity

Abstract: A simple method for preparing nanocrystalline C–N-codoped TiO2 photocatalyst was developed by annealing titanium carbonitride. The prepared C–N-codoped TiO2 powders were characterized by TGA, XRD, XPS, UV–Vis, PL, SEM, and BET surface areas. The photocatalytic activity was evaluated by the photocatalytic degradation of methylene blue in an aqueous solution under visible-light radiation. Results showed that the annealing temperatures and time affected the crystal composition and structure and activity of the catalyst. The most promoting effect of C–N-codoping in activity was obtained over C–N-codoped TiO2 prepared by annealing titanium carbonitride at 400 °C for 8 h. The high photocatalytic activity could be attributed to the synergetic effects in light absorption and the suppression of recombination of electrons/holes pairs.
