From armor plating to photocatalysis : Two photocatalysts based on boron carbides, B 4.3 C and B 13 C 2 , are reported. The more stable and efficient B 4.3 C exhibits H 2 evolution rates of about two orders of magnitude higher than graphitic C 3 N 4 , and without the need for noble metal cocatalysts. Also, both materials can act as photocathodes for photoelectrochemical water reduction under visible light irradiation.
