“…Recently, Tang et al. reported a novel material composed of WO 2 –Na x WO 3 ( x >0.25) hybrid conductor materials for IR‐light water splitting . In addition to the tungsten conductive oxides, other hybrid conductive oxides MO 2 –A x MO 3 (M=V, Mo, Ta, Re, Nb, Tc, Ru; A=Na, K, Sr; x = not defined) are proposed to potentially have similar photocatalytic properties.…”

The development of artificial photosynthetic systems for water splitting and CO2 reduction on a large scale for practical applications is the ultimate goal towards worldwide sustainability. This Concept highlights the state-of-the-art research trends of artificial photosynthesis concepts and designs from some new perspectives. Particularly, it is focused on five important aspects for the design of promising artificial photosynthetic systems: 1) catalyst development, 2) architecture design, 3) device buildup 4) mechanism exploration, and 5) theoretical investigations. Some typical progress and challenges, the most significant milestones achieved to date, as well as possible future directions are illustrated and discussed. This Concept article presents a selection of new developments to highlight new trends and possibilities, main barriers, or challenges; with this, we hope to inspire more advances in the field of artificial photosynthesis.

“…This allows for a controlled plasmon tuning over a wide spectral range via chemical treatment, either during synthesis [1,8,26] or post-synthesis, [11][12][13]22] making these materials very appealing for numerous applications. [10,[27][28][29][30][31][32][33] In vacancy doped semiconductors and in particular in copper chalcogenides, plasmon tuning goes in hand with redox-chemical reactions and a simultaneous removal/insertion of copper, as well as structural changes of the crystal lattice. [11][12][13] In metal oxide nanostructures instead the incor-poration of additional carriers can also be induced by capacitive charging.…”

“…The main effect responsible for the improved performance was related to plasmon induced hot electron injection from the ITO NCs to the single layer graphene in combination with the light confinement effect of the supporting Ge nanoneedle array [291]. The works highlighted above highlight the possibility to exploit the NIR LSPR for light harvesting upon plasmon induced hot carrier extraction in the NIR [33,271,292]. As also shown for example, in Cu 2-x S nanoplate/reduced graphene oxide electrodes serving as active electrocatalysts for the oxygen reduction reaction [143].…”

production from the NIR plasmon resonance or bio-medical applications in the biological window. In 2 this review we highlight the recent advances in the synthesis of various different plasmonic semiconductor NCs with LSPRs covering the entire spectral range, from the mid-to the NIR. We focus on copper chalcogenide NCs and impurity doped metal oxide NCs as the most investigated alternatives to noble metals. We shed light on the structural changes upon LSPR tuning in vacancy doped copper chalcogenide NCs and deliver a picture for the fundamentally different mechanism of LSPR modification of impurity doped metal oxide NCs. We review on the peculiar optical properties of plasmonic degenerately doped NCs by highlighting the variety of different optical measurements and optical modeling approaches. These findings are merged in an exhaustive section on new and exciting applications based on the special characteristics that plasmonic semiconductor NCs bring along.
