“…H 2 ‐TPD and CO 2 ‐TPD were utilized to assess the absorptive property of the prepared catalysts. The strong adsorption ability of the catalyst for molecular H 2 and dissociated atomic hydrogen is beneficial to the hydrogenation of activated CO 2 species to form methanol ,. The H 2 ‐TPD profiles for the reduced catalysts is presented in Figure a.…”

CO 2 hydrogenation will be essential for a sustainable society if methanol and CO can be efficiently obtained using appropriate catalysts. In this paper, a highly efficient CuZnCeO x catalyst was synthesized using a parallel flow coprecipitation method, and was evaluated in CO 2 hydrogenation to produce methanol and CO. Interestingly, the catalyst shows excellent activity and stability, and the selectivity of the products can be controlled by the amount of CeO x . Characterization results show that a significant synergistic effect between Cu and metal oxides (ZnO and/or CeO x ) was observed at the composite catalysts. Cu plays a critical role in the activation of H 2 , and CeO x strongly adsorbs CO 2 . CeO x improved the dispersion of Cu nanoparticles and promoted the spillover of atomic hydrogen, which was beneficial to the generation of methanol. Meanwhile, ZnO exhibited weak adsorption ability for CO 2 , which was beneficial for the generation of CO. In addition, ZnO can significantly improve the dispersion of the CeO x nanoparticles. Both the dispersion of active sites and the activation abilities of CO 2 are critical for catalyst activity and product selectivity. Thus, the ternary catalyst CuZnCeO x shows higher performance than the binary catalysts (CuZnO x and CuCeO x ) in the CO 2 hydrogenation reaction. This paper provides a viable way to produce selectively methanol or CO from CO 2 hydrogenation.[a] Dr.

“…The unique emission properties make thin‐film BP a promising active gain medium in MIR lasing devices. [ 208,209 ] Huang et al reported a BP‐based MIR surface‐emitting laser with an open microcavity architecture, in which the lamellar BP film with air nanogaps were sandwiched between top and bottom SiO 2 /Si 3 N 4 distributed Bragg reflector (DBR) mirrors. [ 208 ] The PL density from lamellar BP is stronger than that from densely squeezed BP flakes, which is attributed to the occurrence of constructive interference induced by periodic air gaps.…”

Black phosphorus (BP), a van der Waals (vdW) layered material, has been intensively studied in recent years since the rediscovery of its thin‐film form in 2014. It is considered as a promising material for mid‐infrared (MIR) photodetection, due to its intrinsic narrow bandgap, tunable band properties, decent optical absorption, high room‐temperature mobility, and high compatibility with silicon‐based technology. Here, the recent advances in the synthesis techniques, the novel optoelectronic properties, and applications of thin‐film BP flake in MIR photodetection are reviewed. Over 17 synthesis techniques of BP films, as well as their merits and drawbacks, are summarized and discussed. The recently discovered strain‐, electric‐field‐, and chemical‐doping‐induced bandgap tuning effects in BP effectively extend its optical absorption cutoff wavelength into regime with longer wavelength (>4 µm). In addition, the establishment of BP‐based vdW heterostructures paves a new way to design novel high‐performance MIR photodetectors. BP MIR photodetectors enabled by various photocurrent generation mechanisms (photoconductive, photogating, and photovoltaic effect) and device configurations (transistor‐type, waveguide‐coupled, Schottky‐junction‐type, and heterojunction‐type devices) are summarized and compared.

“…In recent times, BMW has developed iDrive system which is an informatics system which uses various sensors, tags to track the location of vehicle and to assess the condition of road and provide directions to the driver [34]. Zhang and others [35] designed a system that monitors temperature and humidity inside the refrigerator truck by using sensors, RFID tags, and wireless communications technology. Companies like Apple and Google are moving ahead with autonomous or driverless cars using IoT in transportation.…”
