Zr-Al co-doped SrTiO3 with suppressed charge recombination for efficient photocatalytic overall water splitting.
2021
Zr–Al co-doped SrTiO3 with reduced Ti3+ concentration demonstrates more than 2 times enhancement compared with Al-doped SrTiO3 in photocatalytic overall water splitting. Systematic studies reveal that the co-doping of Zr4+ can reduce the substitution of Ti4+ by Al3+ and effectively suppress the formation of charge carrier recombination centers (Ti3+).
