Study On Synthesis And Spectroscopic Properties Of Boron Dehydrogenation And 1,8 - Naphthyl Derivatives Derived By CoP Nanoparticles

Hydrogen has been seen as the best alternative energy sources to meet the growing demand of an efficient and clean energy supply. In the fuel cell based hydrogen economy have a widely known technological barriers,such as controlled storage and release of hydrogen.Recently, the ammonia-borane(AB, H3NBH3) complex was identified as one of the leading candidates as a hydrogen reservoir owing to its high gravimetric hydrogen capacity of 19.6 wt %, stability, water solubility, and nontoxicity.The release hydrogen from AB has two primany ways, catalytic thermolysis and catalytic hydrolysis. The pyrolysis of AB, hydrogen is not fully released, and it usually requires high temperature released more hydrogen from AB and hydrogen is commonly released at a relatively low rate. In contrast, the hydroiysis of AB can proceed rapidly and generate three equivalents of H2 at room temperature, provided that suitable catalysts are employed. This interesting character has driven more and more people to develop novel catalysts for enhanced hydrolysis efficiency of AB. The tested in the catalyst system,platinum has shown the highest catalyst activity in this hydrolysis reaction. However, platinum is a precious metal, so in practical application the cost is high. Many people have motivated the search for a low cost catalyst for the same hydrolysis reaction In this work, we report a topotactic synthesis of cobalt phosphide nanoparticles and discuss their active catalysis for H2 release from the hydrolysis of AB at ambient conditions. These include temperature, catalyst concentration, and the concentration of Ammonia borane impact on the catalytic activity.The CoP NPS is the first time for hydrolytic dehydrogenation of ammonia-borane, and its catalytic activity is higher.Because of 1,8-naphthyridine and its derivatives with the special N-hybrid conjugate π electronic structure,it have good photophysical and photochemical properties. Ruthenium(II) complexes with d6 electronic structure exhibit metal to ligangd charge-transfer(MLCT) spectroscopic properties, and they have significant photochemical and photophysical properties upon excited state. Based on the advantages, we design and synthesis two 1,8-naphthyridine derivatives and two Ru(II) complexes, and complexes structurally characterized by 1HNMR and MS,and investigate spectoscopic properties of these compounds.
