In the development of direct methanol fuel cell (DMFC) the fabrication of an anode comprising of a Pt or Pt-based bi or tri-metallic alloys nanoparticles on a suitable support material having higher stability, higher surface area, electrical conductivity and strong interaction is very important. In the present work we have solved this problem by using a nanocomposite of reduced graphene oxide (rGO) and graphitic carbon nitride (g-C₃N₄) as the support material and deposited PtCo nanoparticles by chemical reduction. The electro-oxidation of methanol is carried out in an acidic medium.

Unlabelled: COVID pneumonia patient presents with fever, cough, and breathing difficulty. Many respiratory pathogens have such clinical presentations and pulmonary tuberculosis (PTB) is one of them, which is prevalent in the Indian subcontinent. Herein, we are presenting a case of dual infection with severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) and drug-resistant PTB [likely multidrug resistance (MDR)] in a patient with chronic kidney disease (CKD) and type 2 diabetes mellitus, a clinical course further complicated by a prolonged viral clearance.

The higher methanol utilization efficiency in direct methanol fuel cell (DMFC) is one of the key parameter to show the performance of an anode catalyst. Here in, we have synthesized a highly efficient and stable PtCo anode nanocatalysts (2-4 nm size) supported on reduced graphene oxide (rGO) for the electro-oxidation of methanol in a DMFC. Three different compositions of anode catalysts PtCo (1:7)/rGO, PtCo (1:9)/rGO and PtCo (1:11)/rGO comprising of 20% metal loading by weight of rGO are being investigated for methanol electro-oxidation in acidic medium with different methanol concentration using cyclic voltammetry.

Incomplete methanol oxidation and rapid activity degradation of electro-catalysts are key barriers to successful commercialization of direct methanol fuel cell (DMFC). To address these problems, we report the synthesis of platinum-copper (PtCu) alloy nanoparticles supported on nitrogen doped reduced graphene oxide (N-rGO) as the anode catalyst for the efficient electro-oxidation of methanol. Catalysts with varying molar ratios of PtCu were fabricated using impregnation reduction method and their electrochemical performance was compared with the commercially available Pt/C (20 wt%) anode catalyst.
