The hydrogen tungsten bronzes HxWO3 are promising materials because of their potential applications in hydrogen technology. Their potential applications are related to the collective behaviour of the hydrogen sub-lattice within the bronze crystal structure. From the neutron Compton (NCS) scattering point of view, it is the ability to track the emergence of an ordered behaviour out of individual interactions that seems to be intriguing. For the NCS study, we propose to use a Pd-decorated cubic polymorph of WO3 (c-WO3) as staring material for the bronze formation, rather than the monoclinic WO3 polymorph typically used for the purpose.
