Here, building on our previously reported ambient, water-assisted eco-LAGent synthesis of Cu-BPDC and Zn-BPDC MOFs, we formulate these materials as Nafion-bound films on fluorine-doped tin oxide (FTO) electrodes and evaluate their photoelectrochemical behavior. The resulting electrode platform enables a controlled comparison of the two MOFs under matched coating, electrolyte, and illumination conditions. The combination of earth-abundant Cu and Zn with the carboxylate ligand biphenyl-4,4\u2032-dicarboxylate (BPDC) provides a chemically matched platform for comparing a redox-active Cu-BPDC MOF with a closed-shell Zn analogue under the same coating, electrolyte, and illumination geometry. Comparable scan-rate cyclic voltammetry (CV) showed a broad Cu-associated redox feature for Cu-BPDC, whereas Zn-BPDC remained comparatively featureless over the same potential window. Under chopped-light chronoamperometry (CA) at +0.449 V versus RHE, Cu-BPDC generated a sustained cathodic response of +0.448 \u00b1 0.009 \u03bcA cm\u20132 when plotted as \u2212\u0394j, while Zn-BPDC, bare FTO, and Nafion\/FTO controls showed only weak responses under identical conditions. Optical measurements showed similar apparent direct-transition band gaps for Zn-BPDC and Cu-BPDC (\u223c4.00 eV), whereas distinct solid-state photoluminescence (PL) profiles indicated that optical absorption alone does not account for the different photoelectrochemical behaviors. These results support a Cu-centered photoinduced charge-transfer response in Cu-BPDC films and establish a controlled platform for interrogating metal-node-dependent photoelectrochemistry in MOF-based electrode coatings.<\/jats:p>","DOI":"10.1021\/acs.jpcc.6c04739","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T14:02:49Z","timestamp":1790344969000},"page":"14040-14049","source":"Crossref","is-referenced-by-count":0,"title":["Cu-Enabled Photoinduced\nCharge Transfer in Green-Processed\nCu-BPDC Metal\u2013Organic Framework Films on FTO"],"prefix":"10.1021","volume":"130","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-7469-9108","authenticated-orcid":true,"given":"Md Zahidul","family":"Hasan","sequence":"first","affiliation":[{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gan","family":"Xu","sequence":"additional","affiliation":[{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kuo-Hao","family":"Chen","sequence":"additional","affiliation":[{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angira","family":"Roy","sequence":"additional","affiliation":[{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helen","family":"Qin","sequence":"additional","affiliation":[{"name":"University of Michigan , , , ,","place":["Ann Arbor, Michigan, United States, 48109"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengjia","family":"Xiang","sequence":"additional","affiliation":[{"name":"Rock Bridge High School , , ,","place":["Columbia, Missouri, United States, 65203"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Yang","sequence":"additional","affiliation":[{"name":"Rock Bridge High School , , ,","place":["Columbia, Missouri, United States, 65203"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5985-3222","authenticated-orcid":true,"given":"Yangchuan","family":"Xing","sequence":"additional","affiliation":[{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary","family":"Baker","sequence":"additional","affiliation":[{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]},{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3018-3608","authenticated-orcid":true,"given":"Zhongyu","family":"Yang","sequence":"additional","affiliation":[{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]},{"name":"University of Missouri-Columbia , , , ,","place":["Columbia, Missouri, United States, 65211"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,25]]},"reference":[{"issue":"4","key":"2026100809085481300_cit1","doi-asserted-by":"publisher","first-page":"1847","DOI":"10.1039\/C2CS35223K","article-title":"Powering the future of molecular\nartificial photosynthesis with light-harvesting metallosupramolecular\ndye assemblies","volume":"42","author":"Frischmann","year":"2013","journal-title":"Chem.
