Abstract

An approach has been made to convert Black carbon (BC) into two-dimensional novel Graphene nanosheets (GNS) by simpler approach carried-out for the conversion of facile using Black carbon (BC) by purging Catalytic-Chemical vapor deposition (C-CVD) technique. Iron and Nickel (Fe-Ni) bi-metallic catalyst supports 92 % GNS yield, as opposed to other lower yields method and using less-cost effective catalysts. The synthesized GNS is employed for the photo-catalytic degradation of Rhodamine-B (RhB) in addition with Janus Green (JG) in a single step which resolves two organic dye contaminant issues with non-toxic molecular intermediates at the same time, under influence of solar light exposure. The Anti-bacterial properties activity of selected gram-negative and gram-positive and fungal activity was systematically achieved. GNS is highly stable and shows less toxicity against the Human embryonic kidney (HEK-293) cell lines and safer to the environment. Furthermore, regeneration efficiency of GNS, which was still at its higher value even after five consecutive cycles of recycling testing, GNS can perform the quite superior result than the earlier reported studies on structurally altered graphene and other graphitic based materials. The fusion of these investigations introduces a new course, promising way to achieve the new era in environmental remediation and utilization of these materials in future eco-friendly approaches.
