As reported by Neaţu et al., Au and Cu species were deposited on TiO 2 nanopartcles stepwisely followed by calcining in H 2 atmosphere to form Au-Cu alloy (Neaţu et al., 2014). In this case, Au is served as visible light harvester due to its LSPR effect while Cu can covalently bind with CO reduced from CO 2 and direct the generation of CH 4.
