A new nitrogen rich porous organic polymer for ultra-high CO2 uptake and as an excellent organocatalyst for CO2 fixation reactions

Introduction

Over the past few decades with the advancement of human civilization and industrialization the concentration of greenhouse gases in the atmosphere have increased significantly [1]. Carbon dioxide is one of the most important among the greenhouse gases [2]. The burning of fossil fuels along with global population blast, are considered to be the top contributors of CO₂ emission [3]. Besides that, forest fire and burning of organic materials [4] contribute largely in increasing the abundance of atmospheric CO₂. The rapid raise in CO₂ concentration in air is creating major critical issues like global warming, ocean acidification and climate change [5]. According to international energy agency (IEA) there is approximately 0.7 ℃ rise in global temperature than that of the 1961–1990 baseline, which is serious threat to mankind [6]. Thus, mitigation of the increasing trend of CO₂ concentration in air is a key concern to scientists and environmentalists across the globe.
