Semiconductors harness the power of light to conduct molecular transformations, enabling photocatalytic fuel synthesis, including hydrogen peroxide from oxygen. Despite well-documented performances, dependence on critical raw materials in semiconducting particles raises doubts regarding sustainability processes. In recent years, there has been an emerging trend utilize organic semiconductors, covalent frameworks and carbon nitrides as heterogeneous photocatalysts; however, their scalability, synthetic conditions, synthesis temperatures hamper widespread availability. Benzoxazine resins are cross-linked thermosetting mainly studied potential replacements for epoxy resins. this work, production employing benzoxazines metal-free polymeric photocatalysts is monitored, efficiency by means chemical structure curing studied. Cured aromatic benzoxazine affords a higher performance, compared linear or uncured analogues.
