Graphene-based materials have emerged as promising candidates among catalysts for CO<sub>2<\/sub>RR. However, improvements in reaction kinetics and products selectivity are still needed, along with efforts to streamline catalyst synthesis, which remains energy and resource intensive. In this study, a simple, sequential electrodeposition method was developed to synthesise metal nanoparticles (Sn or Cu) directly onto reduced graphene oxide (rGO) on glassy carbon (GC) supports. Through adjustment of the deposition conditions, metal nanoparticles were deposited on the surface of GC electrodes, modified with rGO, resulting in a significant performance enhancement of the CO<sub>2<\/sub>RR compared to the control tests. Not only rGO allowed an increase of electrode surface area available for nanoparticle deposition (up to 760% increase relative to the GC support area), but it also enhanced the catalytic activity through metal-support interactions. The Sn<sub>120\u202fs<\/sub>\/rGO<sub>40cyc<\/sub>\/GC composite achieved formate production rate of 0.110\u202fmmol\u202fh<sup>\u22121<\/sup>\u00a0cm<sup>\u22122<\/sup>, corresponding to 66% faradaic efficiency (at \u22121.4\u202fV\u00a0<em>vs<\/em>\u00a0RHE and a current density of 8\u202fmA\u202fcm<sup>\u22122<\/sup>), while the Cu<sub>60\u202fs<\/sub>\/rGO<sub>40cyc<\/sub>\/GC electrode exhibited potential to generate a broader range of products, including carbon monoxide, formate, ethylene and methane. Although noting that further improvements are needed, this work provides a straightforward method to synthesise effective electrodes using an efficient, rapid, and cost-effective approach, demonstrating versatility in producing a wide range of CO<sub>2<\/sub>RR products achieved via the controlled deposition of metal nanoparticles on\u00a0<em>in-situ<\/em>\u00a0rGO.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-4b5ca52f ts-col-stretched-none ts-bg-color-over-image elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"4b5ca52f\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-9f20216 ts-bg-color-over-image\" data-id=\"9f20216\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-f75bec1 elementor-widget elementor-widget-accordion\" data-id=\"f75bec1\" data-element_type=\"widget\" data-widget_type=\"accordion.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-accordion\">\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-2591\" class=\"elementor-tab-title\" data-tab=\"1\" role=\"button\" aria-controls=\"elementor-tab-content-2591\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">Informaci\u00f3 addicional<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-2591\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"1\" role=\"region\" aria-labelledby=\"elementor-tab-title-2591\"><table style=\"border: hidden;\">\n<tbody>\n<tr style=\"border-bottom: 1px solid #efefef;\">\n<td align=\"right\" width=\"200\"><strong>Year:<\/strong><\/td>\n<td>2026<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #efefef;\">\n<td align=\"right\" width=\"200\"><strong>Authors:<\/strong><\/td>\n<td>Helena Matabosch Coromina, Gaia Boniardi, Chiara Limonta, Bogdan C.
