Herein, highly efficient and cost effective solar photocatalytic water splitting for hydrogen (H₂) generation was achieved by modified g-C₃N₄. Visible light absorption of g-C₃N₄ was enhanced by decorating g-C₃N₄ matrix with silver nanoparticles (Ag). Moreover, incorporation of carbon nanotubes (CNTs) in Ag/g-C₃N₄ facilitated photocatalytic performance through efficient separation and transfer of photogenerated e-h pairs (charges) in Ag/g-C₃N₄ that consequently generated very pure and significant H₂. Among several tested ratios (wt. %) of Ag/g-C₃N₄/CNTs, 1.82 (Ag/g-C₃N₄) and 2.00 (and Ag/g-C₃N₄/CNTs) were found to be highly efficient that harvested maximum visible-light and produced H₂ @1.48 mmol h⁻¹ and 1.78 mmol h⁻¹. We witnessed distinctive role of CNTs as an electron collector and carrier to separate photogenerated e-h pairs to facilitate photocatalysis for H₂ generation together with possible utility of Ag and CNTs doped materials with regard to energy transformation.

在此，通过改性的gC ₃ N ₄，实现了用于产生氢气（H ₂）的高效且具有成本效益的太阳能光催化水分解。通过用银纳米颗粒（Ag）装饰gC ₃ N ₄基质，可以提高gC ₃ N _4的可见光吸收率。此外，将碳纳米管（CNT）掺入Ag / gC ₃ N _4中可通过有效分离和转移Ag / gC ₃ N ₄中的光生eh对（电荷）来促进光催化性能，从而产生非常纯净和显着的H ₂。在Ag / gC ₃ N ₄ / CNTs的几个测试比率（wt。％）中，发现1.82（Ag / gC ₃ N ₄）和2.00（以及Ag / gC ₃ N ₄ / CNTs）是高效的，收获量最大。可见光并产生H ₂ @ 1.48 mmol h ^-1和1.78 mmol h ^-1。我们目睹了CNTs作为电子收集器和载体的独特作用，以分隔光生的eh对以促进光催化H ₂生成，以及在能量转换方面可能使用了Ag和CNTs掺杂的材料。
