Solar energy-driven H₂O₂ photosynthesis from water and oxygen using Ba-implanted ordered carbon nitride

H2O2, a green oxidant and clean fuel, is in high demand across chemical industries, environmental treatments, and even aerospace. However, traditional production methods rely on energy-intensive processes that are not environmentally friendly. Scientists have been seeking a greener alternative, and semiconductor photocatalysis using solar energy to drive chemical reactions has emerged as a promising solution.
