Annotation	Gas sensors are nowadays an integral part of everyday life. New materials and fabrication processes allow the production of smaller, more accurate, cheaper, and more selective sensors. Here, gas sensing parameters of PtSe2, MoS2, and their heterostructures with nanocrystalline diamond (NCD) were measured at room temperature for oxidizing (NO2) and reducing (NH3) gases. The PtSe2 and MoS2 were prepared directly on SiO2/Si or NCD/SiO2/Si substrates by a simple selenization and a carbide-free one-zone sulfurization method. Advantageously, prepared heterostructure enhanced the gas sensing parameters and showed a notable electrical response to the examined gas types at room temperature.
