Abstrakt:	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. [ABSTRACT FROM AUTHOR]
