We report the tunable in-plane photonic spin Hall effect (PSHE) for Laguerre-Guass mode (LGM) at the glass-air interface coated with ReS2-graphene Heterostructure (HS). It is found that the in-plane PSHE can be effectively modulated via altering the topological charge of the incident LGM and the rotation angle of the ReS2 near the critical angle. Interestingly, we find the anomalous enhanced in-plane PSHE far from the critical angle with specific polarization angles, which raises from the sharp decrease of the reflection coefficient for the circularly polarized components. Our results will provide an useful insight for the adjustment of the in-plane shifts of PSHE.
