Abstract: ...
Constructing near-infrared light (NIR) light-enhanced room temperature gas
sensors is becoming more promising for practical application. In this study,
learning from the structure and photosynthetic process of chlorophyll thylakoid
membranes in plants, the first “Thylakoid membrane” structural formaldehyde
(HCHO) sensor is constructed by matching the upconversion emission of the
lanthanide-doped upconversion nanoparticles (UCNPs) and the UV–vis adsorp-
tion of the as-prepared nanocomposites. The NIR-mediated sensor exhibits
excellent performances, including ultra-high response (Ra / Rg = 2.22, 1 ppm),
low practical limit of detection (50 ppb), reliable repeatability, high selectivity,and broadband spectral response. The practicality of the NIR-mediated gas sensor is confirmed through the remote and external stimulation test. A study of sensing mechanism demonstrates that it is the UCNPs-based light transducer produces more light-induced oxygen species for gas response in the
process of non-radiative/radiative energy transfer, playing a key role in significantly improving the sensing properties of the sensor. The universality of NIR-mediated gas sensors based on UCNPs is verified using ZnO, In2O3, and SnO2 systems. This work paves a way for fabricating high-performance NIR-mediated gas sensors and will expand the application fields of NIR light.

Abstract: ...
It is a great challenge to develop efficient room-temperature sensing materials
and sensors for nitric oxide (NO) gas, which is a biomarker molecule
used in the monitoring of inflammatory respiratory diseases. Herein,
Hemin (Fe (III)-protoporphyrin IX) is introduced into the nitrogen-doped
reduced graphene oxide (N-rGO) to obtain a novel sensing material HNGethanol.
Detailed XPS spectra and DFT calculations confirm the formation
of carbon–iron bonds in HNG-ethanol during synthesis process, which
act as electron transport channels from graphene to Hemin. Owing to this
unique chemical structure, HNG-ethanol exhibits superior gas sensing
properties toward NO gas (Ra/Rg = 3.05, 20 ppm) with a practical limit of
detection (LOD) of 500 ppb and reliable repeatability (over 5 cycles). The
HNG-ethanol sensor also possesses high selectivity against other exhaled
gases, high humidity resistance, and stability (less than 3% decrease over
30 days). In addition, a deep understanding of the gas sensing mechanisms
is proposed for the first time in this work, which is instructive to
the community for fabricating sensing materials based on graphene-iron
derivatives in the future.

Abstract: ...
Implementing parts per billion-level nitric oxide (NO) sensing at room
temperature (RT) is still in extreme demand for monitoring inflammatory respiratory diseases. Herein, we have prepared a kind of core−shell structural Hemin-based nanospheres (Abbr.: Hemin-nanospheres, defined as HNSs) with the core of amorphous Hemin and the shell of acetone-derived carbonized polymer, whose core−shell structure was verified by XPS with argon-ion etching. Then, the HNSassembled reduced graphene oxide composite (defined as HNS-rGO) was prepared for RT NO sensing. The acetone-derived carbonized polymer shell not only assists the formation of amorphous Hemin core by disrupting their crystallization to release more Fe−N4 active sites, but provides protection to the core. Owing to the unique core−shell structure, the obtained HNS-rGO based sensor exhibited superior RT gas sensing properties toward NO, including a relatively higher response (Ra/Rg = 5.8, 20 ppm), a lower practical limit of detection (100 ppb), relatively reliable repeatability (over 6 cycles), excellent selectivity, and much higher long-term stability (less than a 5% decrease over 120 days). The sensing mechanism has also been proposed based on charge transfer theory. The superior gas sensing properties of HNS-rGO are ascribed to the more Fe−N4 active sites available under the amorphous state of the Hemin core and to the physical protection by the shell of acetonederived carbonized polymer. This work presents a facile strategy of constructing a high-performance carbon-based core−shell
nanostructure for gas sensing.

Abstract: ...
Graphene foams are promising three-dimensional (3D) architectures
with the combination of the intrinsic nature of graphene and unique cellular structures
for various realms. Herein, a facile technique is developed by combining supramolecular
assembly with lyophilization to functionalize graphene with donor−π-acceptor (D−π-
A) molecules and then massively transform the two-dimensional (2D) plane nanosheets
into 3D foams. The as-prepared gas sensors work at room temperature (RT) and reveal
comprehensive gas sensing performance with an ultrahigh response (Ra/Rg = 3.2, 10
ppm), excellent selectivity, and reliable repeatability toward NO2. Notably, a gas sensing
enhancement mechanism with density functional theory (DFT) calculations is proposed
to unravel the synergetic effect of the “Greater Electron Transferring Area” and the specific 3D foam structure for the enhancement
of charge transfer and NO2 adsorption. The combination of supramolecular assembly and the lyophilization technique provides a
strategy to prepare 3D architectural graphene-based materials for high-performance gas sensors and chemical trace detectors.
