, que des hétérostructures anisotropes pouvaient être fabriquées à partir de poudres constituées de particules de BiVO 4 et de CuFeO 2 exposant des faces cristallines bien définies par une méthode de photodéposition utilisant un simulateur solaire comme source de lumière. Tout d'abord, les poudres monocliniques de BiVO 4 et hexagonales de 2H-CuFeO 2 , de morphologie bipyramidale tronquée et nanoplaquette hexagonale, respectivement, ont été préparées par optimisation de voies hydrothermales précédemment décrites (Figure B.1). Ainsi, pour obtenir la morphologie et la dispersité souhaitées de la poudre de BiVO 4 , plusieurs paramètres de réaction ont dû être optimisés, tels que le pH, la quantité de tensioactif, le temps de réaction en autoclave et la vitesse d'agitation en autoclave, Dans le contexte du développement de matériaux efficaces pour la production renouvelable de combustibles solaires, ce travail concerne la synthèse et l'analyse des propriétés aux interfaces de photoabsorbeurs à base d'hétérostructures d'oxydes métalliques pour des applications en craquage photochimique de l'eau

, Nous avons montré que l'argent métallique (Ag) et l'(oxy)(hydr)oxyde de cobalt (CoO x OH y ) pouvaient être déposés sélectivement sur les facettes {010} et {110} de la poudre de BiVO 4 bipyramidale tronquée, respectivement. Le platine métallique (Pt) a également pu être déposé sélectivement sur les facettes {010}, à condition que le pH correct, 2,5 -3,0, soit utilisé pendant la procédure de photodéposition. De plus, la régiosélectivité de la photodéposition de l'(oxy)(hydr)oxyde de nickel, Ensuite, des hétérostructures à base de BiVO 4 ont été préparées par photodéposition, la régiosélectivité du dépôt a été déterminée par microscopie électronique et les espèces déposées ont été analysées par XPS (Figure B.2)
