我们已经成功地构建了一个Z-计划系统，在一个简单的悬浮系统，仅采用金属氧化物光催化剂材料的CO2还原使用水作为电子供体在可见光照射下。Z-方案光催化剂使用SrTiO 3：Rh作为还原光催化剂和BiVO 4作为O2释放光催化剂，通过粒子间电子转移工作，没有电子介体，使用水作为电子供体在可见光下将CO2还原为CO。在SrTiO 3：Rh光电阴极上负载Ag或Au助催化剂可促进CO的光催化还原和光电化学还原。在无电子介体的条件下，pH值为3.5 ~ 5时，SrTiO 3：Rh和BiVO 4颗粒之间聚集良好，通过有效的颗粒间电子转移实现Z-示意CO2还原。值得注意的是，Z-示意图CO2还原仅使用光催化剂粉末，水和CO2进行，因为自pH调节，即使没有任何添加剂诱导SrTiO 3：Rh和BiVO 4颗粒之间的聚集。
We have successfully constructed a Z-scheme system in a simple suspension system employing only metal oxide photocatalyst materials for CO2reduction using water as an electron donor under visible light irradiation. The Z-scheme photocatalyst using SrTiO3:Rh as a reducing photocatalyst and BiVO4as an O2-evolving photocatalyst working via interparticle electron transfer without electron mediators reduced CO2to CO using water as an electron donor under visible light. Loading a Ag or Au cocatalyst on SrTiO3:Rh enhanced CO formation in the photocatalytic CO2reduction and also photoelectrochemical CO2reduction employing a SrTiO3:Rh photocathode. The suitable pH for Z-schematic CO2reduction without electron mediators was 3.5–5 at which SrTiO3:Rh and BiVO4particles aggregated well with each other, resulting in the achievement of Z-schematic CO2reduction by efficient interparticle electron transfer. It is notable that the Z-schematic CO2reduction proceeded using just photocatalyst powders, water, and CO2because of self-pH-adjustment even without any additives inducing aggregation between SrTiO3:Rh and BiVO4particles.
