Efficient Electrochemical CO2 Reduction via Nickel−Nitrogen Sites Hollow Carbon Spheres

After 19th century, carbon dioxide (CO2) and other green house gases has increased more amount of heat which have “trapped” in the earth's atmosphere and automatically global temperature rises. It causes significant climatic changes as well as the amount and frequency of precipitation. It can also increases in extreme weather conditions such as flooding, droughts, hurricanes, and wildfires. It also effects in ecosystem changes, rising sea levels, and food insecurity.
