Ammonium molybdate tetrahydrate (AMT, (NH₄)₆Mo₇O₂₄·4H₂O, 99%) was obtained from Alfa Aesar. Aniline (C₆H₇N, 99.5%), phytic acid (PA, C₆H₁₈O₂₄P₆, 90%), ammonium persulfate (APS, (NH₄)₂S₂O₈, 98%), and hydrochloric acid (HCl, 36–38%) were purchased from Shanghai Lingfeng Chemical Reagent, Shanghai Macklin Biochemical, Aladdin Industrial Corporation and Shanghai Titan Scientific Co., LTD, respectively. The commercial Pt/C (20 wt%) catalyst was obtained from Johnson Matthey. All the reagents were used as received without further treatment.

In total, 60 mg of PC, 0.3 mmol of iron (III) nitrate nonahydrate (Alfa Aesar Co., Ltd.), and 6.7 mmol of α-D-glucose (Sinopharm Chemical Reagent Co., Ltd.) were dispersed in 5 mL of ultrapure water, and sonicated for 30 min to get a homogenous black suspension. The slurries were harvested after washing with water and drying at 60 °C, and then grounded together with melamine (Alfa Aesar Co., Ltd.) at a mass ratio of 1:5. The obtained powder was placed into a tube furnace and heated to 800 °C under Ar flow (100 sccm). After 2 h of pyrolysis, the black Fe–NC SAC was obtained. M–NC SACs (M = Mn, Co, Ni, Cu, Mo, and Pt) were prepared via the same procedures, except for using manganese nitrate hexahydrate (Alfa Aesar Co., Ltd.), cobalt nitrate hexahydrate (Alfa Aesar Co., Ltd.), nickel nitrate hexahydrate (Alfa Aesar Co., Ltd.), cupric nitrate hemipentahydrate (Alfa Aesar Co., Ltd.), ammonium molybdate tetrahydrate (Alfa Aesar Co., Ltd.), and (hydro)chloroplatinic acid (Alfa Aesar Co., Ltd.) as the metal precursor, respectively.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
