Hydrogels containing nanoparticles also exhibit promising potentials in catalysis, wastewater treatment, and organic synthesis. Inspired by the multifunction of gallol presented herein, a simple one\u2010pot method to produce a gallol\u2010tethered gelatin hydrogel via Schiff base under oxidizing conditions using various oxidants is presented. The hydrogels prepared by NaIO<jats:sub>4<\/jats:sub>\u2010induced cross\u2010linking present a high self\u2010healing rate (up to 84.5%), injectable ability, tunable mechanical property, flexible viscoelasticity, and macroporous structure owing to the combination of covalent cross\u2010linking and supramolecular interactions. HAuCl<jats:sub>4<\/jats:sub> contributes to the 3D structure formation of the gelatin hydrogel via oxidation cross\u2010linking. It is reduced by the gallol groups to produce nanogold (AuNP)\u2010decorated hydrogel (Au\u2010gel). This Au\u2010gel is fully characterized by UV\u2013vis, XRD, TEM, SEM, EDX, and ICP\u2010MS and exhibits a high\u2010catalytic activity for the reduction of 4\u2010nitrophenol. The solid Au\u2010gel catalyst is robust, easily recyclable, and reused at least eight times.<\/jats:p>","DOI":"10.1002\/macp.201800427","type":"journal-article","created":{"date-parts":[[2018,11,9]],"date-time":"2018-11-09T13:13:25Z","timestamp":1541769205000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Gallol\u2010Tethered Injectable AuNP Hydrogel with Desirable Self\u2010Healing and Catalytic Properties"],"prefix":"10.1002","volume":"220","author":[{"given":"Qiuxia","family":"Zhao","sequence":"first","affiliation":[{"name":"Key Laboratory of Leather Chemistry and Engineering of Ministry of Education Sichuan University  Chengdu 610065 China"},{"name":"National Engineering Laboratory for Clean Technology of Leather Manufacture Sichuan University  Chengdu 610065 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengdong","family":"Mu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Leather Chemistry and Engineering of Ministry of Education Sichuan University  Chengdu 610065 China"},{"name":"National Engineering Laboratory for Clean Technology of Leather Manufacture Sichuan University  Chengdu 610065 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiong","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Leather Chemistry and Engineering of Ministry of Education Sichuan University  Chengdu 610065 China"},{"name":"National Engineering Laboratory for Clean Technology of Leather Manufacture Sichuan University  Chengdu 610065 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guirong","family":"Qiu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Leather Chemistry and Engineering of Ministry of Education Sichuan University  Chengdu 610065 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2258-3126","authenticated-orcid":false,"given":"Didier","family":"Astruc","sequence":"additional","affiliation":[{"name":"ISM, UMR CNRS N<sup>o<\/sup> 5255 Univ.
