To meet the energy demands artificial photosynthesis is playing the most promising role these days. Using sunlight directly in a manner that can provide useful chemicals is a sustainable means of generating energy. Studies are going on in this context to make better and effective photocatalyst. In this paper, we study the synthesis of flower-like graphene quantum dots-based fuschin (GQDF) photocatalyst from lemon_, which is created by a green and sustainable process that is effective and environment friendly. The UV-visible spectra of prepared GQDF showed a high molar extinction coefficient. A flower-like GQDF photocatalyst has better catalytic efficiency for the selective creation and regeneration of the NAD(P)H cofactor. A newly designed flower-like GQDF photocatalyst is used as one of its most effective photocatalysts as they have several additional applications in the removal of CO₂ and aqueous contaminants like heavy metals.

高效类花石墨烯量子点基复辛光催化剂用于太阳光照射下选择性 NAD(P)H 辅因子再生

为了满足能源需求，人工光合作用如今发挥着最有希望的作用。以可以提供有用化学物质的方式直接利用阳光是一种可持续的能源发电方式。在这种情况下正在进行研究以制造更好和更有效的光催化剂。在本文中，我们研究了以柠檬为原料合成花状石墨烯量子点基复辛（GQDF）光催化剂_，它是由有效和环境友好的绿色和可持续过程创造的。制备的 GQDF 的紫外-可见光谱显示出较高的摩尔消光系数。花状 GQDF 光催化剂对 NAD(P)H 辅助因子的选择性产生和再生具有更好的催化效率。一种新设计的花状 GQDF 光催化剂被用作其最有效的光催化剂之一，因为它们在去除 CO ₂和重金属等水污染物方面具有多种附加应用。
