3D N-heterocyclic covalent organic frameworks for urea photosynthesis from NH3 and CO2
Introduction
Urea serves as the most critical nitrogen fertilizer to meet the needs of a growing population1,2,3,4.

Currently, industrial urea production is still dependent on the Bosch-Meiser two-step synthesis reaction consuming NH3 and CO2 under high temperature and pressure5,6,7,8,9. This complicated urea production process is energy-intensive, consuming ca.
30 billion kJ of energy and emitting ca. 2 tons of CO2 for every ton of urea10.

As a result, adapting the core synthesis chemical reactions to achieve efficient urea production under mild conditions with less energy requirement and environmentally friendliness becomes a promising alternative to conventional ones11.
Photocatalytic technologies driven by solar energy are expected to show great potential for energy-saving production of zero-carbon urea via CO2 coupled with nitrogenous substances12,13. Quite recen
