• . Plasmonic-metal nanostructures are also promising for increasing the conversion efficiency of solar energy directly into chemical energy (see review in [7]), such as in plasmon-enhanced water splitting. These systems depend on the close interaction between metallic nanoparticles and semiconductors

• attracted an enormous interest due to a large variety of promising applications in areas such as nanoelectronics, biotechnology, magnetism, thermoelectrics, solar cells, and water splitting, among others [1][2][3][4]. Their reduced size, elongated geometry, and high surface-to-volume ratio turn nanowires

• phonon scattering come into play. 2.5 Semiconductor nanowires Semiconductor nanowires are excellent candidates to be functional elements in applications as diverse as optics, sensorics, and electronics, and energy applications such as thermoelectrics and hydrogen generation by water splitting [2][3][4

• and conical geometry are promising electrodes for field emission, photovoltaic applications, water splitting, or surface-enhanced Raman spectroscopy [112][113]. The individual cones potentially combine the advantages offered by the reduced dimensions of the tip with the enhanced mechanical stability

The successful synthesis of the present novel nanoarchitectured MgTa2O6 film significantly promoted the potential property of MgTa2O6 as a photocatalyst, which we believe could find practical applications

• in heterogeneous photocatalysts and solar-induced water splitting. Conclusion Well-crystallized MgTa2O6 films with ordered mesoporous structures, imposed by randomly but homogeneously distributed round concaves, were synthesized through evaporation-induced self-assembly followed by calcination at
