The superior mineralization potential of a graphitic carbon nitride/titanium dioxide composite and its application in the construction of a portable photocatalytic air purification system against gaseous formaldehyde

This study highlights the superiority of g-C 3 N 4 /TiO 2 as an S-scheme photocatalyst with the enhanced intrinsic redox capabilities to actively mineralize gaseous formaldehyde (FA) across varying humidity levels at low-power UV light irradiation (1 W).
