This paper demonstrates eggshell membrane protein hydrolysate (ESMH), a critical food waste worldwide, can be harnessed as a multifunctional agent for eco-friendly reduction and functionalization of graphene oxide (GO) based on its diverse and abundant functional groups. The resulting GO reduced and functionalized with ESMH (ESMH-RGO) exhibits an aqueous dispersibility and applicability as a 2-dimensional support for synthesis of catalytic Au nanoparticles (Au NPs) with a high density. The AuNPs synthesized on ESMH-RGO (AuNPs@ESMH-RGO) presents a high catalytic activity for conversion of environmental pollutant (4-nitrophenol) to an industrially useful raw material (4-aminophenol). Those results clearly indicate that ESMH has a strong potential in environmental and materials chemistry.

本文论证了蛋壳膜蛋白水解物 (ESMH) 是一种全球重要的食物垃圾，基于其多样化和丰富的官能团，可用作多功能剂，对氧化石墨烯 (GO) 进行环保还原和功能化。所得的用 ESMH 还原和功能化的 GO（ESMH-RGO）表现出水分散性和适用性，作为合成高密度催化金纳米粒子（Au NPs）的二维载体。在 ESMH-RGO (AuNPs@ESMH-RGO) 上合成的 AuNPs 具有将环境污染物（4-硝基苯酚）转化为工业上有用的原料（4-氨基苯酚）的高催化活性。这些结果清楚地表明 ESMH 在环境和材料化学方面具有强大的潜力。
