Crystalline graphitic carbon nitride is an excellent photocatalyst for hydrogen production due to its non-toxicity, stability, elemental abundance, and visible-light response. Herein, we present a new type of composite photocatalysts, eco-friendly bamboo-charcoal-loaded nitrides accelerate the separation electron-hole pairs. The suitable loading bamboo charcoal on shows increased specific surfa...

Carbonaceous materials are practical anodes for lithium-ion batteries. Commercial graphite anode has a limited theoretical capacity of 372 mAh g−1. Amorphous carbon could break the limitation anode, while nitrogen doping plays critical role in effectively enhancing reversible capacities and rate capability carbonaceous anodes. Herein, we propose new strategy synthesizing nitrogen-doped from gra...

Superhard materials like diamond are essential for abrasive or cutting tool applications. In this way, carbon nitrides are of relevant interest because they are expected to exhibit exceptional mechanical properties, high values of bulk modulus being predicted. A smart and simple method was used to synthesize carbon nitrides and allowed elaborating a low-compressibility polymorph. The processing...
