In recent years the demand for green synthesis and green energy has increased immensely. Herein M0 nanoparticles were synthesized using a metal precursor and NaHCO3 under hydrothermal conditions without using any reducing agent. The nanoparticles were characterized using powder X‐ray diffraction (PXRD), scanning electron microscopy (SEM), and energy dispersive X‐ray analysis (EDX). Surprisingly, it found that the Pt and Pd nanoparticles contain a high concentration of carbon. The presence of carbon is also evident from the attenuated transmission resonance infra‐red (ATRIR) spectroscopy. Moreover, acetic acid was detected as a byproduct of the hydrothermal reaction. NaHCO3 can be considered as the dissolution of CO2 in a mildly alkaline solution. Thus, during the reaction, CO2 was converted to carbonaceous material, which can be considered as a fixation of CO2. The synthesized nanoparticles are also efficient catalysts for the electrocatalytic hydrogen evolution reaction (HER). It was found that Ru nanoparticles exhibit the highest activity among the three catalysts studied.

绿色合成用于电催化产氢的M0纳米颗粒（M = Pd，Pt和Ru）
近年来，对绿色合成和绿色能源的需求已大大增加。在此，在水热条件下使用金属前体和NaHCO 3合成M 0纳米粒子，而不使用任何还原剂。使用粉末X射线衍射（PXRD），扫描电子显微镜（SEM）和能量色散X射线分析（EDX）对纳米颗粒进行表征。令人惊讶地，发现Pt和Pd纳米颗粒包含高浓度的碳。从衰减透射共振红外（ATRIR）光谱学也可以明显看出碳的存在。此外，检测到乙酸是水热反应的副产物。NaHCO 3可以看作是CO 2的溶解在弱碱性溶液中。因此，在反应过程中，CO 2被转化为碳质材料，这可以被认为是CO 2的固定。合成的纳米颗粒也是用于电催化放氢反应（HER）的有效催化剂。发现在所研究的三种催化剂中Ru纳米颗粒表现出最高的活性。
