 The new Z-Scheme GC3N5-slash-CDs photo catalyst has been developed to improve the efficiency of solar-to-hydrogen conversion. This material has shown a much higher rate of hydrogen production compared to other materials, with a rate of 7,860-mol H1G1, which is three times higher than that of pure CDs and seven times higher than that of GC3N5 alone. Furthermore, it has also been found that the material has a faster charge separation rate due to its unique structure, which allows for more efficient use of the sun's energy.
