This paper presents a novel approach using the piezoresistive effect of Cu 2 O/CuO nanorods to achieve synergistic photocatalysis. A two-step hydrothermal approach was implemented to fabricate various ratios of Cu 2 O/CuO nanorods by using N 2 purging. The sample comprising 80 at% of Cu 2 O exhibited superior photocatalysis, which was further enhanced by approximately 15% by the piezoresistive effect. This was attributed to the band gap modulation of the Cu 2 O/CuO nanorods under applied stresses. The sample also demonstrated excellent stability in a photoelectrochemical cell.
