Key Findings

01Pristine CN and MoO3 exhibited low photocatalytic performance.
02Copolymerized CN materials and their heterojunction composites with MoO3 showed substantial performance enhancements.
03The CN-PA400/MoO3 (6%) composite achieved the highest hydrogen production rate (127.22 μmol/h), nearly 6.8 times higher than pure CN.
04The CN-PA400/MoO3 (6%) composite achieved 99.3% methylene blue degradation in 1 hour and maintained over 95% effectiveness through four cycles.
05Enhanced efficiency is attributed to improved heterojunction design, better charge separation, reduced recombination, and increased visible-light absorption.
