“…Anodic aluminum oxide (AAO) is a common, cost‐effective, highly ordered porous membrane material, and has been widely used in sensing, molecular separation, catalysis, and template synthesis [10] . Parameters such as pore size, pore spacing and channel type of AAO can be controlled by changing the type and concentration of the anodizing electrolyte [11] . In 2016, Zhu et al .…”

The rational design of nanoarray‐structured catalysts is an accessible way to increase light absorption ability and boost photothermal CO2 conversion efficiency. However, practical application of current nanoarrays is hindered by complex synthesis procedures, high costs, and low catalyst yields. Herein, we report a simple, robust method to prepare efficient photothermal catalyst by sputtering Co nanoparticles on commercial anodic aluminum oxide (AAO) membrane. The detailed study shows that gas diffusion and catalytic activity can be affected by AAO structures, such as channel size and shape. The optimized Co@dpAAO catalyst reached a record Co‐based photothermal CO2 conversion rate of 1666 mmol ⋅ gCo−1 ⋅ h−1. This study not only provides a facile way to synthesize efficient catalysts, but also promotes the understanding of constructing nanoarray‐based photothermal catalysts.

Anodic aluminum oxide (AAO) templates have been intensively investigated during the past decades and have meanwhile been widely applied through both sacrificial and non-sacrificial pathways. In numerous non-sacrificial applications, the AAO membrane is maintained as part of the obtained composite materials; hence, the template structure and topography determine to a great extent the potential applications. Through-hole isotropic AAO features nanochannels that promote transfer of matter, while anisotropic AAO with barrier layer exhibits nanocavities suitable as independent and homogenous containers. By combining the two kinds of AAO membranes with diverse organic and inorganic materials through physical interactions or chemical bonds, AAO composites are designed and applied in versatile fields such as catalysis, drug release platform, separation membrane, optical appliances, sensors, cell culture, energy, and electronic devices. Therefore, within this review, a perspective on exhilarating prospect for complementary advancement on AAO composites both in preparation and application is provided.

“…Следует отметить, что работ по исследованию сенсорных устройств к аммиаку, построенных на различных физических (оптических) принципах, опубликовано незначительное количество. Известна работа [12], в которой исследовались сенсорные устройства, изготовленные из гибридных композитов Fe 3 O 4 /MW-CNT-PhCOOH с различным содержанием железной окалины при низкой температуре, а также некоторые другие [13,14].…”

Spectral optical properties of synthesized ceramic nanoporous membranes based on anodic aluminum oxide coated silver in saturated ammonia gas flow have been experimentally investigated. Based on the measured transmission spectra and detected interference part of the spectra in wavelength range from 550 to 900 nm, temporal and spectral dependencies of the effective optical thickness and its changes in non-equilibrium conditions were obtained due to adsorption of ammonia molecules on silver film surface. According to detected and measured interference maximum shifts up to 14 nm in transmission spectra of Al2O3 + Ag membranes in ammonia gas flow, the possibility of constructing a selective interferometric optical sensors with 10 − 15 min response time is shown.
