The Cost

Renewable and sustainable energy has an evolving story as the ongoing trade war in the word is influencing crude oil prices. Moreover, the global warming is an inevitable consequence of the worldwide increasing rate of fossil fuel utilization which has persuaded the governments to invest on the clean and sustainable energy resources. In recent years, the cost of green energy has tumbled, making the price of renewables competitive to the fossil fuels. Although, the hydrogen fuel is still extremely expensive compared to the crude oil price, investigations about clean hydrogen fuel production and utilization has been developed significantly which demonstrate the importance of the hydrogen fuel in the future. This article aims to scrutinize the importance of green hydrogen fuel production from solar/wind energy.

Positional Isomerism

In this study, four meso-expanded Co(III)corroles at meta-positions through Suzuki–Miyaura coupling reactions and their structural characterization are successfully accomplished and reported. An analysis of the structure–property relationships by spectroscopy, electrochemistry and electrochemical catalysis demonstrate how the positional isomerism influence the electronic structure and their catalytic behaviors of hydrogen evolution reactions (HERs) and oxygen reduction reactions (ORRs).
