Photocatalytic systems for CO2 conversion to fuels tend to suffer from low selectivity, and sacrificial reagents or external bias are often required to make the reaction work. Now, a wireless and stand-alone photocatalyst device is demonstrated that converts CO2 and water into formate and O2 using solar energy without external bias.

不降低CO 2排放量

用于将CO2转化为燃料的光催化系统倾向于具有较低的选择性，并且通常需要牺牲试剂或外部偏压来使反应起作用。现在，展示了一种无线且独立的光催化剂设备，该设备使用太阳能将CO2和水转化为甲酸和O2，而无需外部偏压。
