Taking <i>C</i>-phenylresorcin[4]arene (RN4) as a model building block, we fabricated a series of porous organic polymers (POPs: RN4-OH, RN4-Az-OH, and RN4-F) where the surface area was enhanced up to ~8 folds (1229 m<sup>2 </sup>g<sup>-1</sup>) than that of the pristine cavitand (156 m<sup>2 </sup>g<sup>-1</sup>). The advantage of connecting the 0D porous cavitands was demonstrated through three environmentally relevant applications, namely, catalytic conversion of CO<sub>2</sub> to value-added products, selective gas (CO<sub>2</sub>, H<sub>2</sub>) uptake, and the charge-specific size-selective separation of organic micropollutants from water. In all the cases, RN4-derived POPs have outperformed the pristine 0D porous macrocyclic cavitand.

The shortage of resources and increasing climate changes have brought the need for sustainable and renewable resources to people’s attention. Biomass is an earth-abundant material and has great potential as a feedstock for alternative fuels and chemicals. For the effective utilization of biomass, this biopolymer has to be depolymerized and transformed into key building blocks and/or the targeted products, and biological or chemical catalysts are commonly used for the rapid and energy-efficient reactions. This Special Issue introduces recent advances in the catalytic conversion of biomass into biofuels and value-added products.

ABSTRACTMuch of the global agricultural by products go waste, especially in developing nations where much of their revenues depend on the exports of raw agricultural products. Such waste streams, if converted to “value added” products could serve as additional source of revenue while simultaneously having a positive impact on the socio-economic well being of the people. We present a preliminary investigation on utilizing chemical activation technique and ball milling to convert agricultural waste streams such as cocoa pod, coconut husk, palm midrib and calabash commonly found in Ghana into ultra-high surface area activated carbon. Such activated carbons are suitable for myriads of applications in environmental remediation, climate management, energy storage and conversion systems (batteries and supercapacitors), and improving crop productivity. We achieved BET surface area as high as ∼ 3000 m2/g.
