chemical lab report:Synthesis and properties of a cobalt cage complexAwad Albalwi
In this experiment [Co(diNOsar)]Br 3 is synthesised from [Co(en) 3 ]Br 3 in the
presence of formaldehyde, nitromethane and sodium carbonate. A yield of
36.7% was obtained for the [Co(diNOsar)]Br 3 .The electrochemical properties
of Co(diNOsar)]Br 3 , [Co(en) 3 ]Br 3 and [Co(sepulchrate)]Br 3 were investigated
by using cyclic voltammetry . The CV spectra of the [Co(en) 3 ]Br 3 complex has
shown clearly reduction of the Co(III) ion to Co(II) ion .However, there is no
reversible oxidation of the Co(II) ion to Co(III) ion. The reason for irreversible
oxidation the Co(II) ion might due to the Co(II) complex exchanging ligands

Maiyalagan,Electrochemical oxidation of methanol on pt v2 o5–c composite cata...kutty79
Platinum nanoparticles have been supported on V2O5–C composite through the reduction of chloroplatinic
acid with formaldehyde. The catalyst was characterized by X-ray diffraction and transmission electron
microscopy. Catalytic activity and stability for the oxidation of methanol were studied by using
cyclic voltammetry and chronoamperometry. Pt/V2O5–C composite anode catalyst on glassy carbon electrode
show higher electro-catalytic activity for the oxidation of methanol. High electro-catalytic activities
and good stabilities could be attributed to the synergistic effect between Pt and V2O5, avoiding the electrodes
being poisoned.
Direct Synthesis Carbon/Metal Oxide Composites for Electrochemical Capacitors...drboon
This paper deals with the study of the carbon/metal oxide composites synthesis for electrochemical capacitor electrode material. Transition metal salts, such as FeCl3 and TiCl3 act as activator in the synthesis of activated carbon from gelam wood sawdust (Melaleuca cajuputi Powell) which also have the functions as substrates for the composites. The surface functionalities of activated carbons were modified using oxidative treatments. The changes on crystallography and surface functionalities were analyzed based on XRD and FTIR data. The electrical conductivities and electrochemical properties were determined using kelvin and cyclic voltammetry methods, respectively. FTIR analyses showed that the activation and oxidation treatments affected their surface functionalities. The XRD analyses showed that oxidative treatments also affected carbons crystallite. The electrical conductivities and electrochemical properties were influenced by their crystallite and surface functionalities. The shape of the cyclic voltammograms varied according to the changes on the surface functionalities and on the metals loading. TEM analyses indicated the existence of nanoparticles metal oxides in the carbon samples.
Role of the morphology and surface planes on the catalytic activity of spinel...Science Padayatchi
The electrocatalytic activity of the spinel oxide LiMn1.5Ni0.5O4 with
different morphologies (cubic, spherical, octahedral, and truncated octahedral) has been
investigated for the oxygen evolution reaction (OER) in alkaline solutions that is of
interest for metal−air batteries. The OER activity increases in the order truncated
octahedral < cubic < spherical < octahedral, despite a larger surface area (2.9 m2 g−1) for
the spherical sample compared to nearly similar surface areas (0.3−0.7 m2 g−1) for the
other three samples. The high activity of the octahedral sample is attributed to the
regular octahedral shape with low-energy {111} surface planes, whereas the lowest
activity of the truncated octahedral sample is attributed to the high-energy {001} surface
planes. The octahedral sample also exhibits the lowest Tafel slope of 70 mV dec−1 with
the highest durability whereas the truncated octahedral sample exhibits the highest Tafel
slope of 120 mV dec−1 with durability similar to the cubic and spherical samples. The
study demonstrates that the catalytic activities of oxide catalysts could be tuned and
optimized by controlling the surface morphologies/planes via novel synthesis approaches.
Use of conventional sources of energy to generate electricity is
increasing rapidly due to growing energy demands. This is a
major cause of pollution as well and also is an environmental
concern for future. Considering this, there is lot of R&D going on in the field of alternate energy sources with recent advancements in technology. One of the most recent advancement is the perovskite solar technology in the photovoltaics industry. The power conversion efficiency of perovskite solar cells has been improved from 9.7 to 20.1% within 4 years which is the fastest advancement ever in the photovoltaic industry. Such a high photovoltaic performance can be attributed to optically high absorption characteristics of the hybrid lead perovskite materials. In this review, different perovskite materials are breifly discussed along with the fundamental details of the hybrid lead halide perovskite materials. The fabrication techniques, stability, device structure and the chemistry of the perovskite structure are also briefly described aiming for a better understanding of these materials and thus highly efficient perovskite solar cell devices. The main focus of this resarch is to understand possible methods to reduce toxicity due to lead and to improve Perovskite stability.
