Heterojunctions based on metal halide perovskites (MHPs) are promising systems for the photocatalytic hydrogen evolution reaction (HER). In this work, we coupled Cs<sub>3</sub>Bi<sub>2</sub>Br<sub>9</sub> nanocrystals (NCs), obtained by wet ball milling synthesis, with g-C<sub>3</sub>N<sub>4</sub> nanosheets (NSs), produced by thermal oxidation of bulk g-C<sub>3</sub>N<sub>4,</sub> in air. These methods are reproducible, inexpensive and easy to scale up. Heterojunctions with different loadings of Cs<sub>3</sub>Bi<sub>2</sub>Br<sub>9</sub> NCs were fully characterised and tested for the HER. A relevant improvement of H<sub>2</sub> production with respect to pristine carbon nitride was achieved at low NCs levels reaching values up to about 4600 µmol g<sup>-1</sup> h<sup>-1</sup>. This work aims to provide insights into the synthesis of inexpensive and high-performing heterojunctions using MHP for photocatalytic applications.
