Together we are stronger' In this work, the preparation of the quaternary nanocomposite TiO 2 /CdS/rGO/Pt is reported along with its application, for the first time, as a catalyst for the photocatalytic reduction of carbon dioxide (CO 2 ) to methane (CH 4 ). TiO 2 /CdS nanoparticles and Pt nanoparticle-decorated reduced graphene oxide sheets (rGO/Pt) were synthesized separately and characterized through X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), Raman spectroscopy, UV-vis spectroscopy and photoelectrochemical experiments. Hydrocarbon samples were collected and analysed using gas chromatography (GC). After 5 hours of illumination under visible light, 0.11 mmol of CH 4 was produced at an average production rate of 0.0867 mmol h À1 , which is higher than the production of CH 4 measured from the TiO 2 /CdS and the TiO 2 /CdS/Pt control samples. The photoelectrochemical experiments confirmed that the presence of rGO sheets in the nanocomposite enhanced the electrochemical and photocatalytic properties of the nanocomposite as a result of rapid electron transport and the inhibition of charge recombination.

“…Additionally, CG electrodes can be easily modified with different species in order to improve their electrocatalytical properties. 4,5 The conductive properties of CG electrode can been enhanced by modifying it with nanoparticles or metallic microstructures, such as: Pt, Ni and Au, [6][7][8][9] which leads to a wide variety of applications, such as electrode materials for supercapacitors, 10 fuel cells, 11 and electrochemical sensors. 12 Microstructures of noble metals, especially gold, have received great interest due to their large electroactive area and electrocatalytic activities.…”

Carbono Grafite Obtido de Baterias de Zinco-Carbono Exauridas Aplicadas como Eletrodo em Sensores Eletroquímicos Resumo: Este artigo descreve a construção de um eletrodo de baixo custo e reutilizável, utilizando eletrodo de carbono grafite (CG) obtido de baterias de zinco-carbono exauridas, modificados com micropartículas de ouro. O eletrodo de CG foi modificado pela eletrodeposição potenciostática de micropartículas de ouro e aplicado como sensor eletroquímico para detecção simultânea de dopamina (DA) e ácido úrico (AU). Os efeitos do tempo de deposição, potencial e concentração do precursor tetracloroaurato(III) de hidrogênio (HAuCl4.3H2O) na formação das micropartículas de ouro foram sistematicamente estudados, utilizando microscopia eletrônica de varredura (FEG-SEM), difração de raios X (XRD) e métodos eletroquímicos incluindo voltametria cíclica e cronoamperometria. Os resultados confirmaram que as partículas de ouro possuem boa atividade eletrocatalítica para a detecção eletroquímica simultânea de dopamina e ácido úrico na faixa de 9,9 a 90,0 mol L-1 para DA e na faixa de 0,13 a 0,51 mmol L-1 para AU com limites de detecção de 2,6 μmol L-1 e 58,9 μmol L-1 , respectivamente. Esses resultados indicaram que o eletrodo CG reutilizado de baterias exauridas, tem potencial aplicação como sensor eletroquímico, além de benéfico ao meio ambiente e de baixo custo.

Micro-/nanoscale noble metal (Ag, Au, and Pt) particle-decorated 3D porous nickel electrodes for hydrogen evolution reaction (HER) in alkaline electrolyte are fabricated via galvanostatic electrodeposition technique. The developed electrodes are characterized by field emission scanning electron microscopy and electrochemical measurements including Tafel polarization curves, cyclic voltammetry, and electrochemical impedance spectroscopy. It is clearly shown that the enlarged real surface area caused by 3D highly porous dendritic structure has greatly reinforced the electrocatalytic activity toward HER. Comparative analysis of electrodeposited Ag, Au, and Pt particle-decorated porous nickel electrodes for HER indicates that both intrinsic property and size of the noble metal particles can lead to distinct catalytic activities. Both nanoscale Au and Pt particles have further reinforcement effect toward HER, whereas microscale Ag particles exhibit the reverse effect. As an effective 3D hydrogen evolution cathode, the nanoscale Pt-particle-decorated 3D porous nickel electrode demonstrates the highest catalytic activity with an extremely low overpotential of -0.045 V for hydrogen production, a considerable exchange current density of 9.47 mA cm(-2) at 25 °C, and high durability in long-term electrolysis, all of which are attributed to the intrinsic catalytic property and the extremely small size of Pt particles.
