Highly Asymmetric Phthalocyanine as a Sensitizer of Graphitic Carbon Nitride for Extremely Efficient Photocatalytic H<sub>2</sub> Production under Near-Infrared Light
Highly asymmetric zinc phthalocyanine derivative (Zn-<i>tri</i>-PcNc) with intense near-IR light (650â800 nm) absorption
is utilized as a sensitizer to extend the spectral response region
of graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) from âŒ450
nm to more than 800 nm. Ultravioletâvisible light (UV-vis)
diffuse reflectance absorption spectra (DRS), photoluminescence (PL)
spectra, time-resolved photoluminescence spectra (TRPS), and energy
band structure analyses are adopted to investigate the photogenerated
electron transfer process between Zn-<i>tri</i>-PcNc and
g-C<sub>3</sub>N<sub>4</sub> on both thermodynamics and dynamics aspects.
After optimizing the photocatalytic condition and adding chenodeoxycholic
acid (CDCA) as coadsorbent, Zn-<i>tri</i>-PcNc sensitized
g-C<sub>3</sub>N<sub>4</sub> photocatalyst shows a H<sub>2</sub> production
efficiency of 125.2 ÎŒmol h<sup>â1</sup> under visible/near-IR-light
(λ ℠500 nm) irradiation, corresponding to a turnover
number (TON) of 5008 h<sup>â1</sup> with an extremely high
apparent quantum yield (AQY) of 1.85% at 700 nm monochromatic light
irradiation. The present work should be the rarely fundamental investigation
on the utilization of near-IR light of solar radiation for the photocatalytic
H<sub>2</sub> production from water splitting over a dye-sensitized
semiconductor
Indirect Detection of Glycosidases Using Amperometry
Glycosidases are essential enzymes
that cleave glycoside bonds.
The presence of glycosidases have been widely used to detect pathogens,
label cells/tissues, and report specific diseases. We have developed
a rapid electrochemical assay to detect glycosidases. Exposure of
electrochemically inactive substrates to glycosidases releases glucose,
which can be measured easily using an electrochemical cell. Five different
glycosidases were detected rapidly within 1 h using disposable electrodes.
This assay could readily be incorporated into repurposed glucose meters
to rapidly detect glycosidases, which in turn could be useful to report
the presence of a pathogen or illness

Covalently Cross-Linked Chemistry of a Three-Dimensional Network Binder at Limited Dosage Enables Practical Si/C Composite Electrode Applications
Currently, Si (or SiOx, 1
x < 2) and graphite composite (Si/C) electrodes
(e.g.,
Si/C450 and Si/C600 with specific capacities of 450 and 600 mAh gâ1 at 0.1 C, respectively) have become the most promising
alternative to traditional graphite anodes toward high-energy lithium-ion
battery (LIB) applications by virtue of their higher specific capacity
compared to graphite ones and improved cycle performance compared
to Si (or SiOx) ones. However, such composite
electrodes remain challenging to practical for implementation owing
to electrode structure disintegration and interfacial instability
caused by a large volume change of inner Si-based particles. Herein,
we develop a covalent-bond cross-linking network binder for Si/C450
and Si/C600 electrodes via reversible additionâfragmentation
chain transfer (RAFT) polymerization. The as-developed binder with
a 3 mol % cross-linker of other monomers [termed P(SH-BA3%)] achieves improved mechanical and adhesive properties and decreased
Si/C anode volume expansion, compared to the linear binder counterpart.
Impressively, the P(SH-BA3%) binder at only 3 wt % dosage
enables 83.56% capacity retention after 600 cycles at 0.5 C in Si/C450
anode based half-cells and retains 86.42% capacity retention at 0.3
C after 200 cycles and 80.95% capacity retention at 0.5 C after 300
cycles in LiNi0.8Co0.1Mn0.1O2 cathode (15 mg cmâ2) based homemade soft
package full cells. This work provides insight into binder cross-linking
chemistry under limited dosage and enlightens cross-linking binder
design toward practical Si/C electrode applications
