Cu 2 O photocatalyst over Gram-negative bacterium and plant pathogen and observed
that count of E. coli bacteria remained unchanged during photocatalytic experiment
in the absence of light and in dark conditions, whereas excellent outcomes are
obtained in case of g-C 3 N 4 /Cu 2 O -45%, resulting in inactivation of 7 log of E. coli
in 120 min, higher than that of pristine Cu 2 O. Similar behavior was observed by Liu
et al. (2019) in case of fungus Fusarium graminearum, in which 89% of fungal
elimination was observed within 5 h of visible irradiations, much higher than that of
bare g-C 3 N 4 and Cu 2 O. Size control and structural alterations are opted to avoid
aggregation of metal oxides using g-C 3 N 4 as a promising surface support Rath
et al. (2018).
