Herein, a promising dual application high\u2010performance electrocatalyst has been developed for hydrogen evolution and methanol oxidation. A low Pt\u2010content nanoalloy co\u2010doped with Cu, Mn, and P is synthesized using a modified solvothermal process. Initially, ultrasmall \u22482.9 nm PtCuMnP nanoalloy is prepared on N\u2010doped graphene\u2010oxide support and subsequently, it is characterized using several analytical techniques and examined through electrochemical tests. Electrochemical results show that PtCuMnP\/N\u2010rGO has a low overpotential of 6.5 mV at 10 mA cm<jats:sup>\u22122<\/jats:sup> in 0.3\u00a0<jats:sc>m<\/jats:sc> H<jats:sub>2<\/jats:sub>SO<jats:sub>4<\/jats:sub> and high mass activity for the hydrogen evolution reaction. For the methanol oxidation reaction, the PtCuMnP\/N\u2010rGO electrocatalyst exhibits robust performance. The mass activity of PtCuMnP\/N\u2010rGO is 6.790\u00a0mA mg<jats:sup>\u22121<\/jats:sup><jats:sub>Pt<\/jats:sub>, which is 7.43 times higher than that of commercial Pt\/C (20% Pt). Moreover, in the chronoamperometry test, PtCuMnP\/N\u2010rGO shows exceptionally good stability and retains 72% of the initial current density even after 20,000 cycles. Furthermore, the PtCuMnP\/N\u2010rGO electrocatalyst exhibits outstanding performance for hydrogen evolution and methanol oxidation along with excellent anti\u2010poisoning ability. Hence, the developed bifunctional electrocatalyst can be used efficiently for hydrogen evolution and methanol oxidation.<\/jats:p>","DOI":"10.1002\/smtd.202301651","type":"journal-article","created":{"date-parts":[[2024,3,10]],"date-time":"2024-03-10T20:11:10Z","timestamp":1710101470000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Hierarchical PtCuMnP Nanoalloy for Efficient Hydrogen Evolution and Methanol Oxidation"],"prefix":"10.1002","author":[{"given":"Padmini","family":"Basumatary","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering Gachon University  Bokjung\u2010dong Seongnam\u2010si Gyeonggi\u2010Do 1342 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji\u2010Hyeok","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Gachon University  Bokjung\u2010dong Seongnam\u2010si Gyeonggi\u2010Do 1342 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimpul","family":"Konwar","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Gachon University  Bokjung\u2010dong Seongnam\u2010si Gyeonggi\u2010Do 1342 Republic of Korea"},{"name":"Department of Chemical and Biomolecular Engineering Yonsei University  Seoul 03722 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anjalu","family":"Ramchiary","sequence":"additional","affiliation":[{"name":"Department of Physics Bodoland University  Rangalikhata Kokrajhar Assam 783370 India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byungchan","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Chemical and Biomolecular Engineering Yonsei University  Seoul 03722 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0214-9701","authenticated-orcid":false,"given":"Young Soo","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Gachon University  Bokjung\u2010dong Seongnam\u2010si Gyeonggi\u2010Do 1342 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,3,10]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201803676"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsmaterialslett.1c00559"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.7b12968"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsenergylett.1c00246"},{"key":"e_1_2_8_5_1","doi-asserted-by":"crossref","DOI":"10.1002\/smtd.202300427","volume":"8","author":"Nguyen T.
