Abstract

Correction for ‘Necessary and sufficient conditions for the successful three-phase photocatalytic reduction of CO2 by H2O over heterogeneous photocatalysts’ by Kentaro Teramura et al., Phys. Chem. Chem. Phys., 2018, 20, 8423–8431.

The authors would like to make the following corrections to their published article:

(1) On page 8424, eqn (5), H2O should be changed to 2H2O as shown in the amended equation below:

 
CO2 + 8H+ + 8e− ⇌ CH4 + 2H2O(5)

(2) On page 8426, line 2 in the right column, the sentence should be amended as follows:

Very recently, we also discovered that the modification of Ga2O3 with Zn species suppresses the evolution of H2 and does not change the formation rate of CO.

(3) The references in Table 1 on page 8426 should be corrected as shown in the revised Table 1 below:
