Rationally designing and optimizing metal-free electrocatalysts for the oxygen reduction reaction (ORR) isof great importance for fuel cells and metal-air batteries, but remains a great challenge. A N,S-codoped graphene-like carbon (GLC) was synthesized by a simple carbon-bath pyrolysis method, in which urea and thiourea (1:1 w/w) were used as both the sacrificial template and source of nitrogen and sulfur, and glucose as the carbon precursor. A mixture of these materials was placed in a crucible that was contained in a larger crucible full of carbon powder. Compared with N-doped or S-doped GLCs synthesized using only urea or thiourea, respectively, the N,S-codoped GLC had a pore volume of 0.63 cm³/g and a larger specific surface area of 583.68 m²/g, the highest micropore to total surface area of 29.39% and micropore to total pore volume of 12.70%, and the highest pyridinic-N and graphitic-N content of up to 92.2%.The N,S-codoped GLC showeda high electrocatalytic activity for ORR with a mid-wave potential (E_1/2) of 0.82 V_RHE, which was more positive than that of Pt/C (E_1/2=0.80 V_RHE) in an alkaline electrolyte. The N,S-codoped GLC catalyst had better stability and superior methanol tolerance compared with commercial Pt/C (20 wt%), abenchmark catalyst.

合理设计和优化用于氧还原反应（ORR）的无金属电催化剂对燃料电池和金属空气电池至关重要，但仍然是一个巨大的挑战。通过简单的碳浴热解法合成了AN，S掺杂的石墨烯样碳（GLC），其中尿素和硫脲（1：1 w / w）用作牺牲模板和氮和硫的来源，葡萄糖是碳的前体 将这些材料的混合物放在坩埚中，坩埚装在装满碳粉的较大坩埚中。与仅使用尿素或硫脲合成的N掺杂或S掺杂的GLC相比，N，S掺杂的GLC的孔容为0.63 cm ³ / g，较大的比表面积为583.68 m² / g，最高的微孔占总表面积的29.39％，最高的微孔占总孔的体积的12.70％，吡啶-N和石墨-N的含量最高，高达92.2％。中波电位（E _1/2）为0.82 V _RHE的ORR的电催化活性，比碱性电解液中的Pt / C（E _1/2 = 0.80 V _RHE）强。与市售Pt / C（20 wt％）基准催化剂相比，N，S掺杂的GLC催化剂具有更好的稳定性和优异的甲醇耐受性。
