Future energy crises and environmental deterioration may only be avoided by converting solar energy into sustainable, safe, cost-effective, and environmentally friendly technologies such as water splitting. Many researchers and governments throughout the globe have stressed the imperative need for affordable, environmental benign, resistive to corrosion, and earth-abundant nanostructured photocatalysts. This has led scientists to look for a green and cost-effective way to generate energy. As a result, the significance of photo catalyst engineering and reactor design difficulties connected to the performance of the photocatalytic reactions, as well as the examination and analysis of photocatalyst behaviors for adaptable and cost effective H2 production, is emphasized and summarized. The carbon-based materials have an appealing band structure, strong chemical stability, is plentiful on Earth, and is relatively easy to produce, making them suitable for hydrogen production. As example, graphene oxide (GO) with the oxygenated functional groups and graphene and its counterparts, including Graphene quantum dots (GQDs), GO, reduce graphene oxide (rGO), have been demonstrated to be ideal nanocomposite materials due to their superior properties and distribution in matrix and CNTs with excellent electronic transmission efficiency, low cost, stability, and environmental friendly are a great alternative of electron mediators for photocatalytic devices to boost light absorptivity for efficient hydrogen generation but some of them have limited photocatalytic activity due to their low sunlight usage efficiency, therefore the numerous methods, such as doping ions, constructing heterostructure, and functionalizing carbon-based materials, have recently been proven to promote the photocatalytic activity of them. The pore structure of carbon material functions as an acceptor of photogenerated electrons, improved the photocatalyst's specific surface area. Generally low-dimensional carbon materials demonstrated immense promise as highly efficient, low-cost, and environmentally friendly catalysts for hydrogen generation as an energy source. This article reviews the recent research progress on carbon-based materials for hydrogen evolution for the first time. It commences with a quick overview of the present state of affairs and fundamental concepts of hydrogen production in carbon-based nanomaterials for use in this field. We anticipate that this study will inspire readers to expand the use of carbon-based materials in H generation in a more environmentally friendly way.
未来的能源危机和环境恶化只有通过将太阳能转化为可持续、安全、具有成本效益和环保的技术，如水分裂，才能避免。全球许多研究人员和政府都强调了需要负担得起、环境友好、抗腐蚀、地球丰富的纳米结构光催化剂。这导致科学家们寻找一种绿色且具有成本效益的方式来产生能源。因此，强调并总结了光催化剂工程的重要性以及与光催化反应性能相关的反应器设计难题，以及对可适应和具有成本效益的 H2 生产的光催化剂行为的检查和分析。
碳基材料具有吸引人的能带结构、较强的化学稳定性、在地球上丰富且相对容易生产，因此适合用于制氢。例如，具有含氧官能团的氧化石墨烯 (GO) 和石墨烯及其对应物，包括石墨烯量子点 (GQDs)、GO、还原氧化石墨烯 (rGO)，由于其优异的性能和在基质中的分布以及 CNTs 中优异的电子传输效率、低成本、稳定性和环保性，已被证明是理想的纳米复合材料，是光催化器件中电子介体的绝佳替代品，可提高光吸收率，从而高效制氢，但由于它们对太阳光的利用率有限，因此它们的光催化活性有限，因此最近已经证明了许多方法，如掺杂离子、构建异质结构和功能化碳基材料，可以提高它们的光催化活性。
碳材料的孔结构作为光生电子的受体，提高了光催化剂的比表面积。一般来说，低维碳材料作为高效、低成本、环保的制氢催化剂具有巨大的应用前景，是一种有前途的能源。本文首次综述了用于制氢的碳基材料的最新研究进展。本文首先简要概述了碳基纳米材料在制氢方面的研究现状和基本概念。我们预计，这项研究将激发读者以更环保的方式扩大碳基材料在 H 生成中的应用。
