Published: December 2018

Herein we report a microwave assisted, fungal extract mediated synthesis of noble metal decorated reduced graphene oxide(r-GO). The carbon to oxygen ratio increased from 1.46 in GO to 2.72 in r-GO. The electron rate transfer capabilities of Pt, Pd, Ru, Pt-Pd and Pt- Ru decorated r- GO were tested in ferri-ferro coupling reaction. Excellent electrochemical behaviour were observed in their ability to oxidize hydrazine, reduce HO, as well as oxygen reduction in alkaline medium and hydrogen evolution in acidic medium. These reactions represent diverse applications in energy production, storage, electrochemical sensing and electro catalysis, thus the method presented here can be quite useful in diverse applications.

This study, we synthesized a graphene oxide@BiBTC MOF (GO@BiBTC) photocatalyst using a hydrothermal method. The resulting samples were comprehensively characterized using FT-IR, Raman spectra, XRD, SEM, TEM, XPS and UV-Vis spectroscopy. The photodegradation reaction fits the pseudo-first-order kinetics and the deterioration rate constants () value of BiBTC, GO@BiBTC MOF composites were 0.

Infrared (IR) photodetectors play an important role in many fields such as industry, medicine, security, Achieving high response and maintaining stability in the device performance while reducing materials cost are required for the practical use of optical sensors. This study presents the development of a low-cost but high-performance IR photodetector based on a hybridization of up-conversion microparticles of NaYF:Tm,Yb (UCMPs) and reduced graphene oxide material (RGO). In this combination, UCMPs play the role of absorbing photons from 980 nm excitation light, generating electron-hole pairs, which are useful for sensing applications.

The development of Pd-based materials with high activity and long-term stability is crucial for their practical applications as an anode catalyst in direct formic acid fuel cells. Herein, we reveal that the catalytic activity of Pd towards formic acid oxidation can be enhanced by incorporation of a series of rare-earth oxides, including ScO, CeO, LaO, and PrO. For example, Pd nanoparticles incorporated with ScO supported on nitrogen-doped reduced graphene oxide (Pd-ScO/N-rGO-, = 1/3, 1/2, 2/3, 1, and 3/2; "" denotes the molar ratio of Pd : Sc) can be obtained using a sodium borohydride reduction method.
